Remote door unit problem

When I use the remote to lock the doors the sound that the unit omits keeps omitting, when I push the unlock everything is normal, any ideas as to why, Thanks

 

Do you mean the truck continues to emit a constant beeeeeeeeep ?

If so make sure the doors are actually shut completely. That will cause it. If the doors are completely shut and it still does it it is probably one of the door switches.

 

Jimmyh, You "Nailed" it. it appeared that all the doors were closed, but one of the access door wasn't quite there, close enough where it would lock, but not closed enough. Thanks!!!
