I've got a 1993 F150 5.0.
I've already go power locks so I'm wondering if it's possible to just install a brain to turn it keyless or if it's much more extensive. Anyone know?
Thanks!

 

I am sure you probably can something aftermarket. But it's a lot of wiring cutting and splicing, and if you find something you are interested in, look up the instructions on the web, and look for anything special for a Ford installation. Fords usually require extra wiring and possibly some relays to make the locks work.

 

Clarion makes one, UNGO Prosecurity P/N K20 Keyless entry system. Easy install. Probably most auto security manufacturers have similar.

 

I put them on my 95. Not hard at all. Some minor wire cutting and splicing down around the passenger kick panel on the relays. JCWhitney kit around 40 bucks.

 

Bulldog Security sells keyless entries AND remote start with harness. Usually no wire cutting involved. I used to take all the time wiring them up manually but since they added the harnesses for most models, I went that way on my 2000 and so I don't use the factory remotes anymore. The OEM remotes won't unlock the doors when the motor's running.

Pretty cheap too.
