Question 1

Are you licensed and insured to work on Nissan vehicles in California?

Accepted Answer

Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services locksmith license, LCO#6792, and carries full liability insurance. For programming work on a vehicle like the 2015 Titan, the job runs through the OBD port using professional-grade equipment, not a generic code reader. Any locksmith you hire for this truck should be able to tell you exactly what tools they use and give you a real quote for a remote head key over the phone. If they can't answer those questions before they show up, that's a problem.

Question 2

How do I spot a scam locksmith before I get stuck?

Accepted Answer

The pattern is consistent. They quote a low number on the phone, show up with no real automotive equipment, and the price doubles once you're standing in a parking lot with no options. With a 2015 Titan specifically, a legitimate locksmith should know this truck takes a remote head key, know the correct battery size, and be able to explain how the immobilizer programming works before they touch anything.

Ask them point blank: what tools do you use to program a Nissan remote head key? If they fumble that answer, hang up.

We document our work on YouTube and TikTok so you can see the actual process before you call. That's the opposite of how a scam operation runs.

Question 3

Will a replacement key work exactly like the original factory key?

Accepted Answer

Yes, when the job is done right. A properly programmed replacement remote head key for your 2015 Titan gets registered to the immobilizer the same way the original was. The truck starts, the lock and unlock buttons work, and the key functions the way it did the day you bought it. Before I leave any job, I walk through every button and start the vehicle at least once to confirm everything is responding. You get a key that's been tested, not just handed over and hoped for.

Question 4

I bought a replacement remote head key online. Can you just program it, or do I need the whole key from you?

Accepted Answer

You can bring your own key in some cases, but there's a catch. The remote head key for this truck has to match the vehicle. If the key you bought has the correct factory FCC ID on the fob and is a genuine unit, it can usually be programmed. If it's a cheap aftermarket clone with inconsistent internals, it may not take a program reliably, and some of them fail outright during the process.

The blade also has to be cut to your specific truck, which requires either pulling the key code or decoding your lock. If it didn't come pre-cut, that's a separate step.

Bottom line: if you already have a key in hand, call me first and describe what you've got. I'll tell you honestly whether it's worth trying to use it or whether you're better off going with a verified unit from the start.

Question 5

My 2015 Titan starts fine but the remote lock and unlock buttons stopped working. What's going on?

Accepted Answer

Nine times out of ten on these trucks, that's the CR1620 battery running low. The immobilizer side of the key pulls less power than the remote transmitter, so the truck will keep starting after the buttons go dead. It's one of those situations where the key feels like it's dying slowly but it's really just the battery going first.

Swap in a fresh CR1620, make sure it's seated correctly with the positive side facing the right direction, and test all three buttons. If the remote functions come back, you're done. If the truck still starts but the buttons stay dead after a new battery, the key may need to be re-registered or there's an issue with the receiver module in the truck. That's where I come in.
