Are You Making The Most From Your Key Repair?
How to Repair a Remote Key
Although most remote key fobs come with impressive battery lifespan, they eventually degrade. Sometimes car key fob repair 's as easy as changing the batteries, but occasionally there are more serious problems.
An easy fix that could help is taking apart the remote by cleaning the buttons and moving them in and out. These steps could be all you need to get your key fob back in working order.
Battery
If the fob is still working you can replace the CR2025 or CR2032 battery. If not, you can inspect the battery terminals or buttons to determine if they are any parts that are loose. Often the terminals and buttons can be re-soldered back into place, but you'll need to be aware of the kind of battery your fob uses.
If you're not sure whether the battery is at fault, make use of a backup fob to unlock or start your car. If it's possible, it's time to replace your primary fob. If not, you will need to have a professional inspect it to determine the issue. It could be as simple as reprogramming, or it could require other types of repair. You may also find that your vehicle has forgotten the fob. This is not something you can fix by yourself.
Case
The outer plastic housing of a remote is known as the case. It is usually equipped with an additional button pad. It is best to use an entirely new case as the original is likely to be very filthy. Additionally, it is vital that the circuit board within the case is correctly placed. The circuit board is responsible for controlling the function of the key fob. You can test it using a multimeter set to RF (radiofrequency) mode and a scanner that is tuned to the same frequency as the key fob.
Check the contact points on the keys on the keypad. They could be loose over time or broken. By carefully re-soldering them back into their original position can usually restore the functionality of the keypad unless they snap off completely.
Buttons
If your key fob buttons aren't working anymore or are difficult to press, you can buy a replacement dorman or Motormite remote key housing on the internet at a an affordable price for your model/year/make. Then, you can take the circuit board out of the old case and insert it into the new one. For certain models, you may need to adjust the position of the board slightly. The black contact points of buttons can be adhered to with aluminum foil and double-sided tape.
Programming
The key fob is paired with the receiver of your vehicle and this connection can become corrupted. A professional will inspect your vehicle to determine its year, make and model. They'll then use special equipment to reconnect or program a blank transponder chip or fob (or clone the key if that is possible). Then, they test the remote to be sure that it works.
It is crucial to be cautious when reprogramming the blank key, because the process can be complicated and different brands require slightly different steps. It is easy to miss a key step or to wait too long to exit the programming mode. To reduce the chance of damaging your car, it is best to work with an expert with vast knowledge of the security system of your vehicle. Certain programming tools that are essential to use can also read diagnostic trouble codes on your vehicle. This can assist you to solve other issues.
