Car Immobiliser Repair

Car immobilisers were a necessity for automakers in the latter part of the 20th century, as hot-wiring cars was becoming increasingly popular among thieves. The immobiliser stops your vehicle from starting if your key fob chip is damaged or doesn't match.

It is therefore essential to repair your car key immobiliser as soon as it becomes faulty or damaged. Here are a few common causes of your car's immobiliser failing to function:

Dead Batteries

A dead battery is among the most frequently cited reasons for key fob issues. Problems with batteries can be caused by long-term use or harsh environmental conditions, or getting older. If a battery fails to function, it is unable to transmit the signal required by the immobiliser, and operate the key fob. This can prevent your vehicle from starting, and will require a professional to repair the immobiliser system.

Most times replacing the battery is all you need to revive an old battery and get it back to working. You can buy a high quality coin-styled battery at your local hardware store, or even from general retailers, for $5-10. After you have purchased a new coin-style battery, remove the old one and open the casing. There's an opening or notch on the seam that separates the bottom and top halves.

If the new battery isn't able to solve the issue, it may be a problem with the RFID system on the key fob itself. Most vehicles with the push-button ignition feature require the fob to be placed close to the barrel of ignition to verify its presence and send the proper signal to allow the vehicle to start. If the RFID on the key fob isn't able to communicate with the vehicle, you'll have to have the key made for your vehicle or take it to the dealership for an immobiliser repair.

This adds a layer of security that greatly reduces the risk of theft and other types of vehicle crime. However, just like any other electronic device transponder keys are prone to a myriad of issues, including those related to the chip's functionality.

Transponder chips are extremely delicate and even a small amount of physical damage can severely affect their capacity to function. This is the reason it's essential to check the transponder chip for signs of wear and tear, because any damage that occurs could be a direct cause of malfunctioning car immobiliser.

This is why it's important to keep your key fob and key chain away from a variety of contaminants and water as much as is possible.

It's also important to keep in mind that a transponder is specifically programmed for a specific vehicle, and modifying any of the parts that are sensitive could cause issues with compatibility that could impact its function.
