1. The Switchblade/Flip Key: Most typical in designs from the late 1990s to the mid-2010s, these secrets feature a folding metallic blade and a three-button remote.
2. The Smart Key (Standard): Used for vehicles with push-button start but without full "Advanced Key" features. The user must push the button on the fob to unlock the doors.

If the car fails to begin and shows a "Key Not Recognized" message, attempt holding the fob against the designated "key sign" on the guiding column or center console. This enables the car to read the transponder chip via induction, even if the fob battery is dead.

2. Physical Button Failure

Gradually, the rubber membranes inside the fob can wear down. If a specific button (like the trunk release) stops working while others function, the internal micro-switch might be harmed. In this case, the shell can in some cases be replaced, however frequently a new fob is needed.

3. Disturbance

High-power radio towers, mobile phone chargers, or perhaps remaining in close proximity to a smartphone in a pocket can sometimes hinder the fob's signal. If the fob isn't working, attempt moving it far from other electronic devices.
