Car Key Fob Repair: What's The Only Thing Nobody Is Discussing
Car Key Fob Repairs
Key fobs today do a lot more than unlock and start cars. This extra complexity can result in costly repairs when it fails.
The good news is that most fobs use flat watch-style batteries that are easy to replace at home. It is possible that a simple reset can make your fob work again.
Battery Replacement
A dead battery is the most frequent reason for the fob's key not working. It's simple to fix and worth trying before you purchase a replacement fob. Simply take my latest blog post to a local auto parts store or hardware retailer that stocks button cells and choose the replacement. You can also consult your owner's manual (or in the event that you don't have one, YouTube is full of videos of people who explain how to do it) for specific instructions for opening and replacing the battery in your particular type of fob.
You'll need to gently pry off the sides of many fobs to access the battery. You'll need a small, flat-bladed screwdriver or another tool with a small blade. It's a good idea to look for a notch on the lower edge of the fob that you can wedge your tool between. You may also want to keep an eye out for small pieces that could come loose while you work.
Install the new battery in the same way as you removed the old one. The positive (+) side should be facing the buttons and the reverse (-) the markings on the battery compartment.
You can push a button to test the fob. If it isn't working, there may be a problem with your car that needs to be fixed or replaced by a professional.
Certain key fobs are difficult to open and their contacts may be fragile and easily corroded. In these cases, the best option is to talk to a expert or a dealer. If you need to replace batteries, you should be gentle and follow the instructions specifically in your owner's manual. You may be able to locate an identical battery at a big-box store or discounter, but make sure to check the owner's manual to make sure it is compatible with your vehicle.
Replacing the Internal Key
To guard against theft, many key fobs have an electronic key inside. When the battery in the fob fails and the key is discarded, a blank one is left behind that can be used to unlock doors and trunks. In some instances the key could even start certain vehicles. Many people don't realize this however they could save a trip to the dealership by simply replacing the fob's battery. The flat watch-style battery is found in most modern fobs. These batteries can be found in auto parts stores and hardware stores. It is essential to choose the correct kind of battery. A bad battery can damage the electronic circuitry and cause the battery to fail earlier.
If you try replacing the battery, and the issue persists, it could be a sign something else is going on with your car. Review the owner's manual of your vehicle to determine if you have a reset procedure that can restore the fob to the factory program. If that doesn't help, you'll need to visit a dealership or an independent shop that specializes in vehicle security systems and fob programming.
Fobs could also fail because of faulty transmitter receivers. These are usually located near the steering wheel or on the dashboard. They transmit signals to allow you to unlock your car and start it with the fob. If you're having to get closer and closer to your car in order to make it work, there's a high chance the transmitter is failing.
It may be necessary for a professional to open the case of the fob to replace the transmitter. A simple screwdriver will usually get the job done however some fobs come with complicated release mechanisms that require a specific tool or equipment that is available only at a dealership. It is a good idea to have a certified mechanic handle this job to ensure you don't damage the fob or injure yourself.
Reprogramming the Key
A key fob that's not working could just require a new battery. These batteries are easily found in home improvement and pharmacy stores and are affordable. This is a great method to start before you purchase an entirely new key fob.
Alternately, you might be able to program the fob by following some basic steps. This procedure can differ between automobiles, so read the owner's manual and study the specific model of your vehicle. For example, one key fob may require that the ignition be on while reprogramming it. One key fob may require the key to be inserted multiple times.
The procedure is easy. Make sure the battery is securely in place. Then, sit in the driver's seat and close all doors EXCEPT for the driver's side door. This will ensure that the new key fob is communicating with the vehicle properly. Put the old key in the ignition, then turn it on but don't start the engine. Press the lock button while aiming the fob towards the receiver for transmission. It is usually located on the front above the mirror. Within a short time frame the key will signal to the vehicle that it's been programmed by turning off the doors locks or emitting a chime. This is a difficult procedure, so pay attention to the timing and don't press too hard the button.
If the key fob still does not work, try reprogramming it again with fresh batteries. If the problem persists you may want to visit your local dealer or locksmith. A professional will have the tools and programming equipment needed to reprogram your car's fob or make a new key if it's required.

However, he's had to turn down customers who have European models due to the fact that there's no equipment required. Most aftermarket fobs can be programmed, but always consult your local dealer to determine the price.
