Before investing money on a replacement, owners should follow this list:
Check the Battery: If the remote doesn't work but the car starts, it is most likely just the button battery.

Q: My key turns in the ignition, but the engine will not crank. Is it the secret?A: If the "CODE" light stays on, it is a key/immobilizer concern. If the light goes out, the issue is most likely the starter motor, battery, or ignition switch.

Q: Can I get a key cut from a photo?A: Yes, modern auto locksmiths have software that can decipher the bitting of a key from a clear, high-resolution photograph.

Q: What should I do if I lose all my keys?A: Do not panic. A mobile auto locksmith professional can open the car without damage, translate the lock to identify the blade shape, and program a brand-new secret into the BCM from scratch. This is more affordable than changing all the locks.

Q: How do I alter the battery in a Grande Punto flip key?A: Flip the metal blade out. You will see a small slotted screw (usually plastic). Turn it to the 'unlock' position, and the battery tray will move out from the bottom or side of the fob.
