Ford keyless entry problems
Sometimes Ford keyless entry problems are as simple as a dead battery in the remote control. Sometimes the remote key fob buttons will fail from normal heavy usage over the years. In that case replacement of the key fob transmitter will be required. But I have found on a few 1994 to 1996 Ford Explorers and Mercury mountaineers, The problem can be much more complicated. There is a technical service bulletin that states that the module that controls the keyless entry system may need to be replaced due to damage from static electricity discharge.
The Ford keyless entry module is located under the driver's seat and attached to the upper portion of seat track. The technical service bulletin states that the upper track is not always grounded to the lower track as an intended. What can happen is the driver that is charged with static electricity will sit down in the drivers seat and send a lightning bolt of static electricity through the keyless entry module? In cases where there is not a good ground between the upper and lower seat tracks, the module could be destroyed.
Ford keyless entry repair
If this condition has already happened to you, then you will have to replace the remote module itself. But even if your system is working okay the following repair is recommended for Explorer models 94-96. Ford has specially designed a clip kit that will simply snap onto the lower track and has a carbon steel finger that will ground the upper track.
The clip does fit very tight against the track, and I use a pry bar to push it into place. It is also recommended to spread generous amounts of silicone grease. Not only on where the clip installs but also where the finger will ride against the upper track. This will insure a strong connection and that corrosion will not weaken it. The official Ford part number for the repair kit is F77Z-78600B86-AA. The kit comes with instructions on where to install the special clip and only costs a few dollars. The replacement part number for the remote module itself is F7CZ-15604-EA on both Ford Explorers and Mercury Mountaineers.
