I have a Maserati GranSport Coupe (2004)
This morning the key was working fine (unlocked doors, unlocked boot, lights blinked). Then suddenly:
1) Key fob stops working -- can not unlock doors or boot. No head/tail lights flashing when pressed.
2) The red light keeps blinking in the front panel (I believe this is the 'armed' light).
I've done the following without success
1) Turned off the battery, waited 15 minutes, turned on.
2) Opened all the doors/boot, tried to press the unlock on the fob.
3) Closed the doors/boot and manually locked them, then pressed the unlock on the fob
4) Tried to press the unlock on the fob while the key was inserted into the driver side lock
5) Tried to press the unlock on the fob while the key was inserted into the ignition
6) Tried to press the unlock on the fob while the key was in the ignition and the car was running.
I have a backup key which was not working (electronically) for some time. I changed the battery and it still does not unlock the boot or cause the front/rear lights to blink. (It's as if it is dead).
I started the engine and drove home (about 40km, staying under 100km and never in gear 4+). It didn't cause any problems. (Not sure if the immobilizer should have done something or not).
So my questions are:
1) Does swapping out the battery on a key fob break the fob? (I.e. it needs to be recoded?)
2) Anyone have any idea why I could drive so far with the red light blinking?
3) Anyone know what I need to do to fix the keys/immobilizer so they work correctly?
All help greatly appreciated!
Thank you.!
