1985 f250 keyless entry

i have been trying to install a audiovox aa-925 alarm for the keyless entry feature, i used the relays as in the reverse polarity diagrams and they work properly. the issue comes when the alarm is hooked up to the relays,the doors lock and unlock, but the actuators keep makin noise like if theyre still tryin to pop. i am really confused here can anyone give me any direction as to what i should be lookin at

are you sure it's a 1985?  I think they started making the f250 in 1987

positive

I would check the output from the alarm, to make sure it's a pulse output and not a constant, with some of those units you can program the output
