I have looked all over and cannot find a solution, maybe I am just not using the right terms.

New to me F250. Keypad did not work when I bought it. Totally unresponsive. I pulled the door panel and it was unplugged. Easy fix right? Well yes but now it unlocks on pressing anything 1-6 without the code and locks while pressing the 7/8 and 9/0 together like normal. Obviously the unlocking is not normal as no code is needed.

Anyone have any ideas?

 

Was probably unplugged since it wasn't working- May be easier to just replace it

Yeah I fear that it might be the case. I unplugged it and then plugged it in without the batteries hooked up, still no effect.
