Car key fob problems and reasons why your car won’t start
These days pretty much any vehicle out there has a microchip in it, the traditional metal keys have been replaced with transponder chip keys and the most recent ones are even newer technology smart keys or proximity keys with the push-to-start button on the vehicle.
The more complex those keys get, they also come with their maintenance, care, and problems as well. In today’s article, we will share some things you probably didn’t know about the key fob you have been using already for years, and how to keep your key in good shape, so you don’t have starting problems with your car or truck.
The most common reasons that your car doesn’t start are below.
With that said, most of the time when we get a call from a customer that their vehicle doesn’t start, we try to determine the problem and the first thing we would ask is if the vehicle has power. If the vehicle has no power, in this case, the owner most likely will solve his problem by himself, and we get good feedback for helping them over the phone without having to drive up to them and charge a service call.
If the car has power then if it’s a smart key fob then you will have to check the key fob’s battery. Fortunately, the battery inside is pretty easily available anywhere and can be replaced. Also, if you do not want to do it yourself you can visit a locksmith shop in your area, and they do offer that kind of service.
We would recommend getting your key fob battery replaced by a professional locksmith, some key fobs could be very difficult to open and if you try to do it yourself with the butter knife you could damage some small components and this is a common scenario in our business, which will cost you much more these fobs are not cheap.
Most of the vehicles give a warning on the dash like a “key battery low” with a key symbol or similar. That means you will have to replace the battery in the key soon.
How do you know if the battery in the fob is low? Well, the smart keys have a small LED indicator light, if the light is not blinking when you press a button on the key that means there is no power or the battery is low.
Also, the proximity function on the key becomes smaller you will have to keep the fob closer to the steering wheel or the remote it doesn’t work from a long distance like before.
Key fob battery is dead
How to start the vehicle if the battery in the fob is dead, and you are stranded? For this situation, the car manufacturers are aware, and they put that info in your vehicle’s manual. Usually, the car has a key pocket in which you can insert the fob there when the battery is dead, and you should be able to start the vehicle and go to the nearest locksmith shop to replace the small battery in the key.
No problem with power
If you don’t have a problem with the power, then most likely the key is damaged or needs reprogramming. The majority of the customers that we get with a situation like that need a new key due to a damaged fob, maybe they drop it too many times and the microchip is bad, or the key got wet, and as with any electronic if it gets water in it, most likely won’t function properly or not at all.
Reprogramming is very rare, even when most of our customers are asking just to reprogram their key back. Of course, when you google this problem: “My car won’t start”, the first answer would be the key needs to be reprogrammed. But this is not fairly true, they most likely need a new key.
Only a few old models have that issue when you disconnect the battery on the vehicle then it will lose the key which requires reprogramming, or also if the vehicle is being without power for a very long time then also will forget the key and will need to be synced back into the system. Reprogramming can be also found on a spare key as well if you have not used your second key in a while, which could cause it to lose programming.
If that is the case with your fob, just give us a call, and we would come to your location and add that key back to the system, so the vehicle can recognize it and you have a duplicate. If the key is damaged, try to call us or your local automotive locksmith to make a new one for you.
Damaged key fob and how to prevent it
The traditional keys are more damage resistant if it’s a plain metal key, the only damage that can be done is if you bent the key, broke it in half, or lose it. If the key is equipped with a transponder chip, those as well are pretty durable, because the microchip is hidden in the plastic head of the key and does not get damaged easily.
In fact, those chip keys are waterproof and shockproof as well, the microchip is sealed and does not get wet or damaged easily like the newer smart key fobs. The newest proximity keys are really fragile and can stop working even if you dos it once. If that’s the case with your fob, contact your local automotive locksmith for a replacement copy.
