Keyless Entry

Keyless entry systems are becoming more popular with car owners due to their ease of use and security features. For example, some models automatically lock or unlock when you touch the door handle, which is much simpler than having to search for keys in your pocket or handbag.

Key fobs can also send a signal to the trunk receiver that can be used for opening the tailgate without touching it.

However, criminals have discovered ways to circumvent these systems. They have been able to utilize software to decode the signals transmitted by key fobs, and even remotely reprogram a new key with the car's transponder code. For this reason, experts advise adding a shielded protection case to your key fob. These cases limit the distance frequencies generated by the fob travel.

If the technician finds an issue, they might require replacing the module.
