You CANNOT program the immobiliser yourself.
A special programming tool is required that only regstered locksmiths carry.
The remote entry can be reprogrammed DIY, but, alas, the immobiliser cannot.
The Liberty can support up to 4 key sets and all must be presented for reprogramming when it is performed.
I had a thrid key made for my Liberty. I bought a second hand key from ebay. That gave me the remote entry fob.
Then I got a key blank off ebay.
The friendly locksmith cut the new key, supplied a new transponder chip fitted the purchased remote entry fob and then reprogrammed all three keys for the remote entry and immobiliser.
He had a special multi vehicle immobiliser "learning-tool" that plugeed into the diagnostic port under the dash.
The remote entry is reprogrammed by connecting two green connectors behind the driver's side footwell scuff plate.
He charged me $90 for the service.
The whole project cost me about $135 for 2nd hand key, key blank and cutting and reprogramming.
