Renault keys are typically reliable, however they undergo everyday abuse– dropped on tough pavement, squeezed into tight pockets, and exposed to extreme temperature levels. Over time, specific elements tend to fail.

The plastic case of a Renault keycard or fob can break or snap, especially if it is sat on or dropped regularly. In addition, the physical emergency blade hidden inside contemporary keycards can become loose or fall out totally if the locking mechanism breaks.
