I think I'm to the point where I feel I can offer up a service to repair broken Keyless entry modules for 88-94 cars
This would be the single plug module for the early cars.
How do I program remotes?
Where is the module??
On coupes and sedans it is on the right rear corner of the interior on the rear package tray.
Convertibles it is on the brace that runs between the rear wheels on the trunk floor.
Availability allowing I can sell you one of the ones I have for $30 provided I get your core module, $50 If I don't (I'd much rather get the core back then the $20)
Or you can ship me your broken module and for $30 I'll fix it and mail it back to you.
Now the problem I am up against in repairing them. So far I have had very good success repairing the modules that are made by TRW. There is another one that is the same externally but does not have the TRW logo on the casing. I can try, and am presently trying to figure out whats wrong with them and how to make them work and work reliably. I'll accept either as a core presently.
Also I will buy unwanted modules. PM me and we can talk.
