A keyless remote fob may seem like a really convenient thing to have – that is, as long as it works. Unfortunately, all of them stop doing their job sooner or later. No matter how careful you are, one time you will try unlocking the doors of your car, and it will fail to open. However, there is no need to panic – although there is a number of reasons why a keyless fob may stop working, in most cases solving this problem is fairly easy and doesn’t require any extraordinary efforts.
1. The Problem Is Not With The Fob
While it isn’t something that happens often, you should still check it so that you don’t waste time-solving the wrong problem. It is quite possible that the problem lies not with the remote but with, for example, car locks (there may be some kind of mechanical or electrical trouble). To eliminate such a possibility take your backup remote (most cars come with two remotes for just that purpose) and try unlocking the door. If you manage to do it successfully, then you will know for sure that something is wrong with your primary remote.
2. The Battery Is Dead
One of the most common reasons why a fob would stop working is just because the battery went dead after prolonged usage – it is something that will happen to every fob eventually. The good news is that most fob batteries aren’t very expensive or difficult to replace. The not so good news is that you have to be very careful when you select – it should be exactly the same as the one originally used by the fob. Otherwise, the replacement is unlikely to work. In other words, if you need a Ford f-150 key fob battery replacement, you should make sure you know what the currently installed one is and find the same model. The necessary information may be found in your car manual or, alternatively, you can contact your local car dealer and ask there. If your fob works after the replacement, the problem is solved, If not, the issue is likely to be with something else.
3. Internal Contacts Are Broken
Although most remote car fobs are pretty sturdy, in the course of their lifetime they are subjected to a great deal of physical abuse. Depending on the make and on how often they are dropped, thrown and bustled around, sooner or later it may turn out to be too much for them. What usually breaks down are battery terminal contacts and the buttons, although many other things can break down. The easiest way to check if this is the case is to take the fob apart and look inside – if the contacts are broken, it can usually be confirmed visually. If you find that this indeed is the case, you may try soldering them back into place – in some cases, it may restore the fob to working condition.
4. The Remote Needs Reprogramming
Originally, a car remote is paired with a specific receiver unit in a particular car – this prevents people with the same make and model unlocking the doors of your car. However, sometimes things go wrong and the remote stops “talking” to the receiver in question. If this is indeed the case, it means that you will have to reprogram your car’s keyless entry system to make it work again. It may sound scary and complicated, but in fact, usually, it is achieved by doing something as simple as getting inside the car, closing the door behind you and inserting the key into the ignition. After turning it from the locked position to the run position and back again several times you will hear a chime. After that, you will have to press the unlock button on your remote, which will be accompanied by the second chime. However, not all cars use this method, so if it doesn’t work, you may have to consult your car dealer about the specifics of the procedure.
If all these methods fail to work, it most likely means that the fault in your car fob is beyond your ability to repair it, and you need a replacement.
