Key fobs not working all of a sudden Lately the battery in the car has been getting low and I had to use my battery charger last weekend to start the car. So tonight I go out to see if it will start and let it run for a bit and the key fob doesnt unlock the door or do anything. I opened the door, Im assuming it let me open it since I had to fob in my hand, and the car started fine.
I let the car run for mins then shut it off. I tried to lock the doors with the fob, nothing happens. So I assume it could be the battery in the fob is out so I go get my spare fob and try it, nothing happens! It worked last weekend. What all of a sudden has rendered both fobs useless? If I lock the door using the switch inside the car, can I get back in it?
Will the alarm go nuts? This is weird. Any input from others? You could try replacing the battery on you FOB's also. It seems unusual that both FOB's battery might go at exactly the same time but I had it happen on one of my cars.
The FOB batterys only seem to last on some of my cars. My bet is on the car battery itself. Once they discharge, weird things happen. You and I have the same Track Pack cars, which means they were built at about the same time. Do you use hibernation mode when not in use?
I always do, as the car usually sits for a week at a time, minimum, even in summer. Put in a new Sears Diehard, couldn't hurt. Replace the keyfob batteries first. I had similar experiences. I couldn't lock the car with the keyfob after driving it, unless I hit the lock button on the door first, and then they keyfob would work.
I also have one main key I use all the time, and another hidden in the house in case I lose the first one so it never gets usedand it failed also.
Doesn't make sense since one is being used, and the other sits dormant, but both batteries were on their way out. Charge car battery, as the battery gets low neither will work ask me how i know.
See my recent thread on key fobs not detected. Not sure it's the same issue but my fix was a warranty claim to replace both fobs and replace WIN module. My issue began with the fob unable to communicate with car to open the hatch and it ended with the car unable to start up.
The gremlins surfaceI had to disconnect my battery and reconnect it. Now my remote start Valet will crank but won't start it. And now the key won't start it either. It'll make really quick clicking noises. Does anyone know what to do? Anyone know how to get the remote start working again? It's an 06 3. And I really doubt I have to get the car serviced again by Circuit City as it is impossible for any car to live it's entire life off of one battery, so a battery reset is bound to happen.
Basically though it seems that you're going to have to enter a code to reprogram the remote to the car or may even have to have it done professionally remember to take all the remotes to the professional. Directed Electronics have a number of Valet models, with different troubleshooting methods due to different built-in feature levels.
The extra detail assists with a quicker solution. Try to establish if the quick clicking noise is coming from the starter motor area.
If it is sounds as if it is, not enough juice getting there. For future reference when removing a battery if it is a 12 volt connect another battery across the terminals you are taking off this will stop you loosing the power to the systems, such as key, radio etc.
Help with remote start after resetting battery?
Parish Lv 4. Answer Save.
Robsteriark Lv 7. Impossible to answer due to insufficient information. What make, year, model and trim level is your car? Is the remote start an aftermarket accessory? If so what's the make and model?
How do I reprogram my Viper alarm after changing the battery?
EDIT: Response to asker's additional info. Which one is yours? Still have questions?While most of these situations apply to any good remote car starter, we specifically discuss the causes and solutions for the Compustar brand.
Mobile edge is proud to offer Compustar at our facility in Lehighton, PA. Browse Compustar remote car starters here. The back of the Compustar remote control shows you how to get your vehicle out of valet mode. Click the photo for a larger image. Symptoms : Lock and Unlock buttons work as normal, but pressing Start does not produce any response from the vehicle. Causes : Someone accidentally pressed the combination of buttons to put the car into valet mode, usually when the remote is in a purse or pocket.
Also, many remote car starters will revert to valet mode when the vehicle is disconnected for service. Any good remote car starter should have some form of valet mode. The remote car starter can be put into this mode to prevent the vehicle from starting remotely while allowing keyless entry and certain other functions to work. You would do this when having service done to your vehicle.
When you press these buttons, the parking lights should flash two times. Press the Start button, and your car should be warm and toasty!
Many times, customers will accidentally bump this switch during day-to-day driving, causing the remote starter to go into valet mode. This is what a properly installed hood pin looks like.
The location of the hood pin can vary from vehicle to vehicle. Note that, in some cases, a tilt switch is used in lieu of a hood pin. Symptoms: Pressing Start results in several flashes of the parking lights but no start. If equipped, Lock and Unlock still function. Any remote starter must have a method of preventing the vehicle from starting when the hood is open. Without this, a mechanic could be seriously injured if the vehicle was remotely started while they were working on it.
In most cases, this is accomplished by a hood pin switch or a hood tilt switch. Either of these devices will tell the car starter when the hood is open.
These devices can fail over time or be broken if a mechanic leans on them accidentally. Replacing the hood switch is a simple matter and can be done at most mobile electronics stores. Symptoms: Pressing any button on the remote results in no response from vehicle. Cause: It is rare, but does happen — in most cases, this is caused by a dead battery in the vehicle or the battery having been disconnected when being serviced.
Remote starters usually have some type of non-volatile memory to retain things like programming features and remote control codes. When this happens, simply call the store that installed it for you.
In some cases, they may be able to tell you how to reprogram it over the phone. Other times, you will have to return to the store for a technician to program it. In any case, this is rare with higher-end remote starters.
Causes: A combination of buttons were accidentally pressed, which put the remote in second-car mode. Again, this is very rare, but happens from time to time. Many remote car starter remote controls have the ability to start two vehicles.The other day my viper pager ran out of power so I changed the battery. Right after I changed the battery I went to test the remote to assure it was corresponding to the alarm; it was not.
Needless to say, I pressed every button on the remote hoping something would happen, but nothing. I wasn't at my house so I attempted everything, I even unlocked the car with my key and tried to start up my car, but that didn't work either. The alarm was terribly annoying and gave me a headache, so I just got a ride and went to retrieve my other pager. Now I only have one responsive pager and I don't want to run the risk of having that one lost or broken.
I've tried to press the lock button several times to "code hop" but that has failed. If anyone has any practice with alarms or has had a similar experience a little help will be greatly appreciated. Update: I attempted the instructions and it somewhat worked.
I still cannot unlock or lock my car with the screen remote, I can only watch the lock icon change. In other words, if I use my secondary remote, the main remote will receive the change. Is there a problem with the remote, or do I have to reprogram it using another method? I'll give you a choice - you can use the instructions posted to Yahoo Answers, or the ones on ehow.Viper Remote Start Error car alarm 5901 & 7752 key fob
Press any button on your car remote while you are holding the "Program" switch and release both buttons. Press the "Program" switch on the Viper alarm's transmitter once more and release it. Remove the key from the ignition and press a button on your Viper remote control to see if the programming worked. Update: Update: I attempted the instructions and it somewhat worked. Answer Save. John Lv 5. Instructions 1 Place your key in your car's ignition and turn the key to the "On" position.

Get your answers by asking now.While this post was written with Viper remote start systems in mind, they can apply to any Directed Electronics product and most all other common brands as well. Below is a list of the 8 most common reasons why your remote start might have stopped working. Read on for explanations on how to identify if one of these applies to your situation and how to fix the problem. If your attempt to remote start the vehicle fails, you might see the parking lights flash a number of times.
This is your remote start system telling you what caused the failure to start. The table below outlines what all of the flash sequences mean.
Viper remote start systems come with a toggle switch that gives you the ability to disable the remote start system at any time. If you had your remote start system professionally installed, the installer should have let you know where they mounted the switch. The toggle switch will only disable the remote start feature of your system. If your system also has alarm and keyless entry features, they will still be functional with the toggle switch in the OFF position.
The fix for this problem is to simply flip the switch back into the ON position. The hood pin on a remote start system is a safety feature that temporarily disables the remote start when the hood is open. This will prevent the remote start from activating if someone is working in the engine compartment. There are several types of hood pins but the most common are the plunger type like the one shown in the picture. They all perform the same basic function which is to provide a ground signal to the remote start system when the hood is open.
This is because the hood pin is also an input that will trigger the alarm when armed. If you suspect you might have a faulty hood pin, you can visually inspect it to see if it is depressed when the hood closes on top of it. Alternatively you can test continuity to ground on the hood pin wire when the hood is closed. The hood pin wire on a Viper remote start system is the grey wire.
The range that your remote will start your car from will diminish as the batteries start getting low and eventually it will stop working all together. The neutral safety wire on the remote start system is a safety feature designed to prevent the remote start from activating if the vehicle is in gear.
It connects to a wire in the vehicle that rests at ground when the transmission is in neutral. And when a remote start is installed on a manual transmission vehicle, the neutral safety wire connects to the emergency brake wire.
You can test to make sure your neutral safety wire is getting a ground signal by testing continuity to ground. Start by replacing the batteries in your remote to rule out a dead battery, but if you still get no response then you might try re-pairing your remote. The foot brake input wire on the remote start is a shutdown input that serves two functions. When you get in, turn the key on, and press the brake to put the car in gear, the remote start shuts down but the vehicle stays running because the key is in the on position.
Its other function is as an anti-theft feature. The foot brake wire one the remote start gets a positive 12 volt signal from the foot brake wire in your vehicle when that brake is pressed.
If the wire is resting at 12 volts due to a short circuit or any other reason, it will prevent the remote start from activating. You can test the foot brake wire with a digital multimeter to make sure that it is not at 12 volts when the brake is not pressed. The foot brake wire on a Viper remote start system is the solid brown wire. Depending on the age of your remote start system, there are a few ways that the remote start can be programmed to detect when the engine has successfully started so it can stop cranking the starter.
Older Viper remote start systems had two options; tachometer tach sensing or voltage sensing. Tach sense is the most reliable method. It uses a tachometer signal in your vehicle that indicates the engines RPMs. Virtual tach works similarly to voltage sense but is much more reliable.
It samples the voltage when you activate the remote start and continues to sample voltage hundreds of times per second to determine when the engine has started. When your system is experiencing tach signal issues, it will usually start and run for a few seconds and then shut down.Enormis Mobile Specialties in Erie, Pennsylvania, has been specializing in remote starters since our inception in Over the years, Enormis has installed thousands and thousands of remote starters and has built a loyal following in northern Pennsylvania.
But what about when you ask your remote start to activate, and nothing happens? When it is winter time, the thought of going out to a frosty, cold vehicle is not very appealing. The good news is that there are six common remote starter issues, but none of them serious. The single biggest thing that can cause a remote starter not to engage is a faulty or missing hood switch. This device gets installed under the hood of your vehicle and prevents the engine from starting when the hood is up.
It is a safety device, designed to prevent your vehicle from accidentally starting when someone is working in the engine compartment, since an injury could occur. The good news is that Enormis can fix this quickly and painlessly. Yes, believe it or not, that remote control on your keychain does take batteries and, after a period of time, they are going to get weak diminishing the range and eventually go dead.
Enormis stocks lots of different batteries, and most likely has the correct ones in stock for you. Maybe you had your batteries replaced recently somewhere other than Enormis, and your remote already quit working again. We have seen batteries installed incorrectly, the wrong batteries installed, insulators removed, or just plain crappy batteries that die very quickly.
If any of these scenarios describes you, we suggest stopping by our store with your vehicle and all of its remote starter remote controls. We can check both of them out for you, and replace batteries if needed. If we find that you need a replacement remote control, we will do our best to find you a new one so you can resume that wonderful feeling of going out to a warm vehicle.
Are you the kind of person who only uses your remote starter when it gets cold outside? If this describes you, then it may have been months since you used it. Is it possible you forget the proper procedure to remote start your vehicle? This is more common than you think. Every fall please check your system and make sure it works! Here is a helpful video on this topic:. What that means to you is your remote starter probably used a data module as part of the installation.
That allows the starter brain to communicate with the vehicle computer in its native language, because it gets programmed with vehicle-specific software. Certain remote starter manufacturers use a safety feature called valet mode. It is designed to temporarily disable the remote starting capability, but valet mode typically leaves the keyless entry function intact. One way you may be able to tell if your vehicle is in valet mode is by watching the parking lights. If they no longer flash when you ask your vehicle to lock or unlock using the remote starter controller, you may be in valet mode.If you shop at Amazon.

Press and hold single button fob, locks lock, get chirp, then instead of starting it just chirps twice. I checked the hood and it's closed. Do I hae tore set something after replacing the battery? TIA, Jason. It should be near the drivers side hood hinge. They could have bumped it while replacing the battery and bent the bracket so the sensor reads open even when the hood is closed From the installation instructions "Install The Hood Safety Switch NOTE: Route the hood safety switch wire carefully avoiding any moving parts or components that can produce excessive heat.
NOTE: Using a piece of convolute adds in the appearance of the installation. NOTE: The switch should be positioned about 30 degrees below parallel to the ground to accommodate for parking on inclines. Member Like Kiwee my mods now contain too many characters to list here. See my build log for details.
Are these instructions from the remote starter install guide? Based on that I would not expect a car without the remote start to have the sensor. The one on my Flex is silver colored metal and should show up against the body color. I get it now.
