killer door locks

I went out to open up my Manta's driver-side door after its winter rest and could not believe how hard I had to turn the key to get it to unlock; tried WD40 in the key opening, but it didn't help.

Locked the door from the inside, tried again and heard something go 'ping', now am unlocking the car from the passenger side.

Since I'm going to have to pull the door panel off to retrieve whatever let loose anyway, could someone tell me what I need to do to get things back to normal?

Thanks,

-John

I finally located my FSM tonight and checked out section 2C on Doors, looks like it is going to be 'remove the door handle' time.

Anybody have any thoughts on a suitable lubricant? It gets COLD here in SD (South Dakota, not San Diego) and it would be nice to use something that doesn't freeze up at minus 30 F.

graphite is a good idea for locks....never use de-icer in your locks...it dries them out.

Word to the Wise

Thanks, defib, for the suggestion.

I pulled off the door panel and fished out the part that went AWOL; looks like I'll be needing the lock actuator off the back of the push button, as this one broke where the lock pin holds everything together.

Didn't take anything else apart as the car sits outside and the door and window need to be in place. If anyone out there has one they'll part with reasonably, please e-mail me...

I pulled the passenger-side door panel and observed how everything works, then used some wd-40 on all the pivot points behind the door latch. This side NOW works like new.

A question to those who have worked on both Mantas and GT's:
How much of the door and lock hardware interchanges between the two models?
