It needs a bit of work to get back on the road, but should come good for a cheap runabout ...

Will add more as time permits / things come to hand.

Looks like you will have to find a friendly Auto Locksmith with the programming tool or bend over for a Dealership.You CANNOT program the immobiliser yourself.
A special programming tool is required that only registered 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 third 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 plugged into the diagnostic port under the dash.
The remote entry is reprogrammed by connecting two green connectors behind the driver's side foot well 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.
And even better with the effort to share the process here!
Yeah - that's not going to happen ...
Ooh this will be interesting!! I’ll get the popcorn
