When I push my remote key fob I can hear a cylinoid clicking in the middle of dash, but my doors will not lock or unluck. It has been get worse over the last few weeks. I have tried both key fobs and they both do the same thing. Have already tried changing the battery. I have a 1999 Ford F250 light duty - any remedy or suggestions would be greatly appreciated!

Thanks

 

Sounds like the door lock acctuators may have died, but both at the same time is kind of unlikely. Have you checked the fuses?

 

Did you ever solve this problem. My 4 door is doing the same thing. It just about HAS to be the relay under the dash.

 

This just happened to my friend with a 2000 F150 Xcab. Both locks stopped working just right after he bought it. Almost as if they just dont have enough power. Dont bother with the relays under the dash, thats the first thing we checked and they all worked fine, we swapped them around and it didnt change a thing. The problem lies elsewhere. He's gonna take it to ford and I'll let you know what they find.


Oh, the truck came with an aftermarket alarm that is controlled by the factory remote, but I doubt it has anything to do with the locks.

 

My 2000 F150 just started that when it gets hot outside. Sometimes it works, and sometimes it doesn't. I am guessing the solenoids are getting weak.

 

Whats the fix? My 250 just started dioing the same thing.

The door lock actuators are like any electric motor, If used enough they tend to burn out or get weak.

Mine went out after my alarm installer was testing it out repeatedly. It had to be done to get the system installed properly. The moter over heats and the insides expand and get stuck. Kinda like a bad starter on your engine!

Well,... Heres a link to a place where you can order replacements CHEAP!!!!!!! They are a heavier duty unit and can ride piggy back on your old door lock rod to make the install easier, and put less strain on it as both activate. This place is awsome for all your electronic supply needs and service is outstanding! I ordered my actuator on a wednesday regular ground shipping and got it on Friday!!!!!!!!!!
