5 Tools That Everyone Within The Key Repair Industry Should Be Making Use Of

How to Repair a Remote Key

Although most remote key fobs boast amazing battery life, they do eventually wear out. Some times it is simple to replace the batteries inside the device, but in other cases the issue could be more severe.

A quick fix that can help is dismantling the remote by cleaning the buttons and moving them in and out. These methods could be all you require to get your key fob back in working order.

Battery

If the fob is still functioning, you can swap out the CR2025 or CR2032 battery. If it's not accessible, you can take it off the fob and check the buttons and battery terminals to look for signs of wear or broken parts. Often the terminals and buttons can be repaired by soldering them back into place but you'll need be aware of the exact kind of battery the fob is using.

If the battery isn't the problem, try using an alternative key fob to determine if you can unlock or start your car with it. If you're able to do so, it's probably time to replace the primary fob. If not, you will require a professional examine it to find the problem. It could be as easy as reprogramming, or it could require different types of repairs. There's also the possibility that your vehicle has lost your fob, which isn't something you can fix on your own.

Case Study

The case of a remote key is the outer plastic housing and typically comes with the button pad replacement. It is recommended to purchase an entirely new case since the original one will likely to be extremely filthy. Also, it is crucial that the circuit board inside the case is placed correctly. The circuit board is responsible for the operation of the key fob and can be tested with a normal multimeter by setting it to the RF (radio frequency) mode and holding a scanner tuned to the same frequency the key fob uses close to it, and listening for signals that pulsate upon button presses.

Another thing to look at is the contact points for buttons on the keypad. These could have become loose or broken in the course of time. A careful soldering process to put them back in place will often restore the functionality of the keypad unless they break completely.

Buttons

If the buttons on your key fob aren't working anymore or are difficult to push, you can purchase a new dorman or motormite remote key housing online at a low cost for the model/year/make. Then, take the circuit board out of your old case and into the new one. For certain models you may have to adjust the position of the board slightly. You can then apply aluminum foil using double-sided tape to stick to the black contact points on the buttons.

Programming

The key fob and receiver in your car are linked however, this connection may be corrupted. A professional will assess the vehicle to determine the make of the vehicle, year of manufacture and model. They employ specialist equipment to re-pair or program the fob with a blank transponder chip (or duplicate a key if this is possible). Then they test the remote to be sure it works.

When reprogramming keys that are blank it is essential to take care. The process is complicated and each manufacturer offers distinct instructions. It is easy to skip a step or wait too long to exit the programming mode. To avoid the risk of causing damage to your vehicle, it is best to employ an expert with extensive knowledge of the security system in your vehicle. Some key programming tools can also identify diagnostic trouble codes in your vehicle. Click On this page can assist you to repair or troubleshoot other issues.
