Case Study

The case of a remote key is the plastic housing that covers the outside and typically comes with a button pad replacement. It is best to use an entirely new case since the original one case is likely to be quite dirty. Also, it is crucial that the circuit board in the case is placed correctly. The circuit board is responsible for the operation of the key fob. It is tested using a standard multimeter by setting it to the RF (radio frequency) mode and holding a scanner tuned to the frequency the key fob is using next to it, watching for pulsing signals when a button presses.

Another thing to look at is the contact points for buttons on the keypad. These might have become loose or broken over time. Soldering them back into place will often allow them to return to their original function, unless they snap completely.

You can then use aluminum foil using double-sided tape to adhere to the black contact points on the buttons.

Programming

The key fob is linked with the receiver of your vehicle, and this connection can be corrupted. A professional will inspect your car to determine its make, year, and model. They will then employ special equipment to reconnect or program the transponder chip with a blank fob (or duplicate the key if possible). They will then test the remote to confirm that it works.

When reprogramming keys that are blank it is essential to take care. The process can be complicated and each manufacturer comes with different instructions. It is also easy to miss a step, or take too long to exit the programming mode, therefore it is recommended to hire professionals with extensive knowledge of the security system of your vehicle to minimize the risk of damaging the car. Some key programming tools can also identify diagnostic trouble codes in your vehicle. This will help you solve other issues.
