306 key replacement

My daughter has just bought a 1998 (S) 306 1.4 maridian. only one key
for central locking. can we get and program a spare. found key on ebay to
buy.
ours is single button IR type and has 2x CR1620 batteries. any ideas
please.

 

Have a look here.

That's only for the 2 button versions, not the single button version
that he has.

If you get one the same on ebay, it's easy enough to pair it to the
car. All you do is put one key in the ignition, turn it (not to
start the engine) and point the new key at the receiver whilst
pressing the button within 10 seconds of turning the ignition on. If
you're pairing two keys (say the existing one and the new one) you
have to do one, then do the other within 10 seconds after that.

Obviously if you've got one key in the ignition, you can't pair that
one, so I think this is in the case of having two remote keys and
one plain.

 

The issue is that the 1998 models have immobilisers, and whilst you may
be able to get the remote to work the central locking, the transponder
in the remote cannot be registered with the ECU without (AFAIK) Peugeot
being involved.

Ah, right of course - I was thinking it was a simple key like my two-
button.
