I have a 2007 Renault Megane 4 door sedan. The ignition keycard has 3 buttons..one for the boot, one for unlocking all doors, one for locking all doors. The battery in it seems fine and works for all functions including ignition, but won’t unlock the car any E dealer wants $732 for a new card and says it takes 4 months to get one . Can I make the unlock function work on the card ?
