Faulty transponder key A transponder key that is defective could have severe consequences.

Transponder keys, like any electronic device, are prone to various problems related to the function of the chip. Transponder chips are delicate, and even a small amount of physical damage can significantly impact their ability to function. This is why it's crucial to regularly inspect the transponder chip for signs of wear and tear since any damage could be a direct cause of a malfunctioning car immobiliser.

Antennas are not bad, but can be bent, pinched or detached from their connectors, causing the RF level of the signal to drop.
