Hi
From what i remember is that you put the key in the ignition and turn it on to number 2 the one just before you start the engine then press the lock button and keep it pressed for about 10 - 15 secs then release the button take the key out shut the doors and try and lock it

i think this is the way hope it works

put key in drivers door lock, turn to lock position while pressing lock button on fob, then turn to unlock position while pressing unlock button on fob , cdl will now work

but it should still work ok after battery change unless u leave them out for a while
