How to Repair a Remote Key
Even though most remote key fobs boast amazing battery lifespan, they eventually wear out. Sometimes it's as easy as changing the batteries, but occasionally there are more serious problems.
Take the remote apart and clean the buttons. Then move them out and in. These techniques might be all you need to get your key fob to work.
Battery
Car key remotes are powered by CR2025 or CR2032 batteries, and they can often be swapped out if the fob is still functioning. If not, look at the battery terminals and buttons to determine if there are any loose parts. You can usually connect the terminals and buttons back in place. However, try what she says 'll have to know the type of battery is used in your fob.
If the battery isn't the problem Try using an alternate key fob to see if you can unlock or start your car using it. If you're able to do so, it's probably time to replace the primary fob.

Case Study
The case of a remote key is the plastic housing that covers the outside and typically comes with the button pad replacement. It is recommended to use the latest case because the one you have case is likely to be quite filthy. It is essential that the circuit board in the case is placed correctly. The circuit board is responsible for the function of the key fob and can be tested using a standard multimeter by setting it to the RF (radio frequency) mode and then holding a radio scanner tuned to the frequency the key fob uses next to it, watching for pulsing signals upon button presses.
Check the contact points of the keys on the keypad. They could be loose over time or have been damaged. By carefully re-soldering them back into place can often return the functionality of the keypad unless they snap off completely.
Buttons
If the buttons on your key fob aren't working or are difficult to press, you can buy a new dorman or motormite remote key housing online at a low cost for your model/year/make. Then, you can take the circuit board out of your old case and put it into the new one. In some cases it may be necessary to move the board slightly. You can then use aluminum foil using double-sided tape to adhere it to the black contact points on the buttons.
Programming
The key fob is connected with the receiver of your vehicle. This connection can be corrupted. A professional will assess the car to determine the make, year and model and employ specialist equipment to re-pair or program an empty fob or transponder chip (or clone a key in the event that it is possible). Then they will test the remote to be sure it functions.
It is important to be careful when reprogramming a blank key, as the process can be complicated and different manufacturers require certain steps that are slightly different. It is also possible to skip a step or take too long to exit the programming mode, which is why it is recommended to hire a professional with comprehensive knowledge of your car's security system to avoid damaging the car. Certain programming tools are also capable of analyzing diagnostic trouble codes from your vehicle. This can assist in fixing or resolving any additional problems.
