Lacquer peeling on a 2007 Mazda MX-5 miata on front drivers wing in two places.

Question edited for clarity.
Question moved to model category.

Yes, you are correct, disconnecting the fuse box has broken the pairing between the key and the immobilizer system. Did you remove the main connection plugs to the fuse box? My thought is that those connectors have never been removed since the car was built and breaking a remaking the connection, you might have some connections that as not as good as they should be. Pull the connectors again and give them a good spray with electrical contact cleaner (that is NOT WD40). Then reconnect.

There is various ideas on resetting the Immobilizer here.

SOUND LIKE HEATER CORE LEAKING .

Get a new key fob and program it using the currently working ones...you will need to have two working sets to program a new one....this will let you know if the boys are worn out...I'd program a third set anyways...just Google how to...for your vehicle.

Sorry to say it but in most cases it needs to be repainted. If you want to try you can lightly sand it and reclear coat it, but if the base coat is causeint it to peal then it needs to be sanded and sealed with a good primer/sealer and repainted.

hey gerry you may need to replace the wheather stripping

There should be screws hidden underneath the cover at the base of the mount for the wing mirrors - if you look around the cover, you should be able to pop it off and get at the screws.
