electric door locks

What is your question?

i can't seem to get my FOB keyless remote to work on my 2003 jaguar x-type, i've programmed it several times as per instructions and even returned it once to warehouse where it was re-checked and returned to me with the statement that this device was working properly. Here's what happens when i lock the vehicle with the door key the security is armed and the locks engage locking the doors, i can open the doors, deactivate security, turn on headlights and unlock trunk with clicker remote but i cannot lock the doors with the remote, in order to lock car doors i must use the key,why?
