2003 Nissan Murano
Key Replacement - Save vs Dealer in Ventura County

Q: How do I know you are not a scam locksmith?

Scam locksmiths follow a predictable pattern: low number on the phone, high number once you are stranded and out of options. They also cannot answer specific questions about your actual vehicle. Ask any locksmith you are considering this before they arrive: what blank does the 2003 Murano remote head key use, and what battery does the fob take. A tech who works on these regularly will answer without hesitation. One who is winging it will go vague or dodge.

Q: Will the replacement key work exactly like the original?

Yes. A properly cut and programmed replacement remote head key for the 2003 Murano functions the same as the factory original. The transponder registers to the immobilizer, the blade works the ignition, and the remote functions respond normally. We test everything on the spot: blade in the ignition, lock button, unlock button, and the third button. The car gets verified running before we hand the key back.

Q: I have a spare key that starts the car but the remote buttons stopped working. Do I need a whole new key?

Probably not. On the 2003 Murano remote head key, the remote functions and the ignition function are separate. The transponder in the blade can keep starting the car just fine while the remote side is completely dead. First thing to check is the CR1620 battery. These drain without much warning and the fob gives you no low-battery indicator.

Q: My 2003 Murano has two keys. If I lose one, does the other one get erased when you program a new key?

No. Adding a key does not wipe your existing working key. All registered keys stay active unless you specifically request an all-keys-lost procedure, which erases everything and starts fresh. If you still have at least one working key, we register the new one alongside it. Both work after. The only time existing keys get erased is if you lost all of them and there is no working key to present during programming.

2003 Nissan Murano Remote Head Key Replacement - Fast, Affordable & Professional

It was a Saturday night in Mission Canyon, the kind where Santa Barbara goes quiet fast once the sun drops behind the hills. A group came out to their 2003 Murano and the remote was completely dead. Doors would not respond, no lights flashing, nothing. They had already tried clicking the fob a hundred times. The car itself was not the problem - just the remote.

They called me mostly out of curiosity, not really expecting much at that hour.

I was already in the area with the right key blank and a CR1620 cell on the van. When I got there the fob shell had a hairline crack along the back seam and the battery had shifted just enough off the contacts to kill everything remote. Popped it open, seated a fresh CR1620, checked the contact clips, and closed it back up correctly.

Then I did what I always do before I hand it back: walked every button, checked the lock, checked the unlock, checked the third button. Tested the blade in the ignition. Everything responded on the first try.

They were back on the road that same night. No tow, no waiting until Monday, no dealer appointment. When the van is stocked and the tech knows the car, a Saturday at 10pm runs the same as a Tuesday morning.

Nissan Murano Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Nissan vehicles?▼

Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services and carries full insurance. For a 2003 Murano remote head key, we carry the right blank, the correct CR1620 cell, and the programming tools to register the key to the vehicle's immobilizer on site. Not every locksmith who shows up with a generic key machine is actually equipped to handle the transponder side of the job.
