If the FCC number on the back of the remote (A) matches the FCC number on the fob for another vehicle (B), then the remote from A can be re-programmed to work with vehicle B.

There's a considerable trade on these on Ebay...for many different makes and models of vehicles. I have a second remote ordered for my Murano - it's coming with instructions on how to program it. I'll post the instructions when it gets here. You don't have to have a dealer program a remote if you have the instructions.

I did a quick search for this, and found these directions at Nissanhelp.com...however, it refers to entering an ID code and a maximum of four codes. That part of the process would require more research.

Here's a link to an old post within this forum:

Interesting! I checked on ebay and found one similar to the ones I have selling for about $25 bucks. I thought they might be worth a bit more than that.

Thanks for the post Pilgrim. The info was very helpful.

 

Glad to help. Just run a Google search on "how to reprogram a Murano remote" and start checking links. You'll find the complete info in no time.

EDIT: I've been searching and between this forum and others, I've found about four variations of how to program the basic remotes - none of which have worked for me. I'm going to keep trying. If/when I find a combination that works in my 07 Murano, I'll post it.

 

Did you ever come up with instructions that worked on programming the key fob? I took my key fob (purchased on ebay) to a very good locksmith with some sort of electronic gizmo that should be able to program the key fobs. He was unable to make it work and said I would need to go to a dealer. The dealer wants about $100 to program it. Thanks!

 

My Murano is an 03. I have programmed my Wife's Infiniti remote to work both cars. I have also programmed my Murano's fob to do the same. I carry the Infiniti remote because it also has the open trunk button.
