'93 306 XDTD locking plips

Have just bought one, and it came with three plips, but only one works. OK
so one had duff batteries, the other two seem to be OK (checked with a
voltmeter).
I tried the proceedure for progamming the two plips, and now the other one
works but the original doesn't.
So, confused, I wonder if anyone knows what I might be doing wrong, or is it
just that I have the wrong plips?
Any suggestions welcome.
Brian.

 

Forgot to mention, these are the two button deadlocking type, which can be
programmed?

 

These can be a right pain to programme. Remove all the metal key parts
from the plips, you need to get as close as possible to the roof
receiver. Use one of the metal key parts and put the ignition to the
accessory position. Then within 10 seconds hold the plips one at a
time next to the receiver, with the side where the metal key went
pointing at the receiver, and push the large button down for two
seconds (until the light stops flashing). Remember all three have to
be done withing 10 seconds. Then switch the ignition off and try them.
You may have to repeat this a few times to get them all working. If
one does not work don't be tempted just to programme that one again by
itself. It will throw the other two out!! Be patient and good luck.

 

Thanks, I will try again.
