Are You Responsible For The Key Repair Budget? Twelve Top Tips To Spend Your Money
How to Repair a Remote Key

Although many remote key fobs have impressive battery life, they will eventually get worn out. Sometimes it's as easy as changing the batteries, but sometimes there are more serious issues.

Take apart the remote and clean the buttons. Then, flex car key repairs in and out. These methods could be all that you need to get your key fob back in working order.

Battery

Car key remotes are powered by CR2025 or CR2032 batteries and they can be swapped out if the fob is still operational. If not, inspect the battery terminals or buttons to determine if there are any loose parts. Often the terminals and buttons can be soldered back in place, but you'll need to be aware of the exact type of battery your fob uses.

If you're not sure whether the battery is at fault then make use of a backup fob to start or unlock your car. If you are able to do so, it's time for a replacement of the primary fob. If it's not then you'll require a professional to assess the fob to identify the issue. It could be as simple as reprogramming, or it could require other types of repairs. You may also find that your vehicle has forgotten the fob. This is not something you can tackle by yourself.


Case

The plastic housing that covers the outside of a remote is called the case. It typically comes with an alternative button pad. It is recommended to purchase the latest case because the one you have case is likely to be quite grungy. It is essential that the circuit board in the case is correctly placed. The circuit board is the main component of the key fob. It can be tested using a normal multimeter by setting it to RF (radio frequency) mode and then holding a radio scanner tuned to the same frequency the key fob operates on 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 could have become loose or broken over time. Soldering them back into place will often allow them to return to full function, in the event that they snap completely.

Buttons

If your key fob buttons are no longer working or are difficult to push, you can buy a replacement dorman or Motormite remote key housing online for an affordable cost for your model/year/make. Then, you can slide the circuit board out of your old case into the new one. It is possible to alter the position of the board on some models. The black contact points of the buttons can be adhered to aluminum foil using double-sided tape.

Programming

The key fob is linked with the receiver inside your vehicle. This connection can be corrupted. A professional will examine the car to determine the make of the vehicle, year of manufacture and model. They employ specialist equipment to re-pair or program a blank fob or transponder chip (or clone a key should this be possible). Then they will test the remote to be sure it works.

When reprogramming blank keys, it is important to take care. The process can be complicated and each manufacturer comes with slightly different instructions. It is also possible to miss a step, or wait too long before exiting the programming mode, which is why it is best to use a professional with comprehensive knowledge of the security system of your vehicle to minimize the risk of damaging your car. Some key programming tools are also capable of analyzing diagnostic trouble codes from your vehicle. This can assist in fixing or resolving any further issues.
