Any suggestions to why I lost the remote key function on my 86 Se?
Battery is good. Last thing I did was install a heater core.
Thanks

The locking mechanism has a slider bar,running right to left and is supported by a plastic clip,this clip becomes dry preventing the door from poping open.You can grease the area whear the clip is,(located about the center of the door).Befor puting the door back together (if you take it apart,remove the outer door skin)Make sure that solves the problem,if it doesnt,then you have a bad actuator,try Fiero store for a new actuator).You might try tapeing a Q-Tip to a long slender stick and greaseing the plastic clip from the outside (Im not sure if you can even see the clip from the outside,top of the door,so good luck).

check to see if your battery is dead in your remote...if not sometimes the battery will move slightly inside the remote itself and then it wont work...tim

Don't know where you have the "brain box" mounted, but you may check to make sure the antenna wire is still fully extended and hasn't become crunched ...

Hi,
What is the brain box and where is it mounted. I just replaced the heater core and maybe casued the problem in the process.
Thanks,

Probably under the dash somewhere. If your Fiero has keyless entry, it isnt stock. Which means someone added it, so it could be anywhere, but most likely under the dash. You may have disconnected it and forgot to reconnect, or accidentally cut a wire. Is it just keyless entry, or also a remote start?

The "brain" is a small black plastic box like an auto alarm. The antenna wire is a single black wire that just hangs from the box and should be routed and secured - not connected to anything. At first glance, it might even look like a ground wire that came off of something. If this wire got ripped off the box, having no antenna it would explain your problem.

Hi folks,
This not a keyless entry system. It is the remote key fob type lock. I have an alarm system on the car that is tied in to the remote key fob bleemer if you will. I pulled the fuse when working on the car because it would set off the security system and cause the car not to start. It's a real pain. I was able to use the remote unlock bleemer with out the security system. I wonder if the lokc opener is part of that chime module mounted next to the bass box under the dash. I had to remove it when I did the heater core.
Hope this helps shed light on my problem. I'm hoping it is an easy fix I am missing. That intermittent horn problem turned out to be anti corrison screws GM used to mount the horn paddle switches.
Thanks,
Dave

Hi folks,
I figured out the problem with the remote. It was a fuse in the security system.
Thanks for your help
