Using newer key fob/key combo on 2003 jeep grand cherokee?
I bought an older jeep for my son after letting him use my wrangler unlimited for a few weeks after he got his license, but he told me how he liked my key, the remote and key are all one, like this
So I looked online and could only find that style key for jeeps newer than his. His jeep has a key/fob like this
Do you think if I bought one for a jeep cherokee but a different model, would I be able to program it to the '03?
I know it's a long shot but I thought I'd give it a chance. Thanks guys!
