Car immobilisers were a necessity for automakers in the late 20th century as hot-wiring vehicles was becoming increasingly popular among thieves. The immobiliser stops your car from starting if the key fob chip is damaged or does not match.

Dead Batteries
A dead battery is one of the most frequent causes of key fob issues. Problems with batteries can be caused by long-term use, harsh environmental conditions or the aging process. When a battery fails, it can no longer transmit the signal required by the immobiliser, and operate the key fob. This can prevent your vehicle from starting and may require a professional to repair the immobiliser system.
Most times, a simple replacement is all that is required to revive a dead battery and get it back to working. A high-quality coin-style battery can be found at your local hardware store or even some general retailers for between $5-10. Once you've purchased a new battery, remove the old one from the fob and carefully open the case. You'll find an opening or notch on the seam separating the top and bottom halves. Push the tip of a flathead screwdriver or coin into the slot, and then work your way around the edges. Then, you can insert the new battery and then snap the two halves of the fob closed. After that you can reuse your old battery at a collection facility close to you.
If the new battery fails to fix the problem, there might be a problem with the RFID technology within the key fob. Most vehicles with an ignition system that uses a push button require the fob to be held up close to the barrel of ignition to confirm its presence and send the right signal to allow the vehicle to start. If the RFID inside the key fob cannot communicate with the vehicle, you'll be required to have a replacement key or take it to a dealer to repair the immobiliser.
If replacing the battery doesn't resolve the problem it's worth taking the key fob apart and examining any buttons that appear to be out of place or broken. It's normal that buttons become misaligned over time, as your key fob is likely to be jostled around a lot.

This adds an extra layer of security, decreasing the possibility of thefts as well as other crimes committed by vehicles. Transponder keys, like any other electronic device, are prone to various issues that are related to the chip's function.

Antennas aren't necessarily good, but they could be bent, pinched or detached from their connectors, which can cause the RF quality of the signal to decrease. Also, you should check if there is any equipment installed between the antenna and the receiver, such as a surge protector or splitter, as this may influence the signal strength.
