Question 1

How do I spot a fake locksmith before I get burned?

Accepted Answer

A few things stand out. First, they won't give you a firm price for your specific vehicle on the phone. They'll say "it depends" and only commit once they're standing next to your car. Second, they show up with no visible company branding and no ID. Third, and this is the one that matters most for an Infiniti: they arrive and then admit they can't actually complete the programming side. Cutting a blade is one thing. Enrolling a key to the immobilizer on a 2015 Q60 requires specific diagnostic equipment and PIN-level security access. If a locksmith can't tell you the process before they start, that's a real problem. Ask them directly: what tool are you using to extract the security PIN and enroll the key? A legitimate tech will answer that without hesitating.

Question 2

What exactly is an emergency key and why does my Q60 use one?

Accepted Answer

The emergency key is the physical blade that tucks inside the fob body. On the 2015 Q60, the main fob handles your remote functions, but that blade is there for when the fob's battery dies and you need to physically unlock the door or turn the ignition cylinder.

What a lot of owners don't realize is that the key isn't purely mechanical. There's a transponder chip in it that the immobilizer reads when you turn the ignition. Cut the blade correctly and the lock cylinder turns fine, but if the chip isn't enrolled to your specific car, the engine won't stay running. The security system rejects it.

So replacing an emergency key on this vehicle is a two-part job: cut the blade to your car, then program the chip through the OBD port. Skip either step and you don't have a working key.

Question 3

What equipment does it actually take to program a replacement key for a 2015 Q60?

Accepted Answer

The short version: professional diagnostic tools with Infiniti-specific programming capability, plus the ability to perform PIN-level security access for this generation's immobilizer.

Infiniti moved to a more involved PIN extraction process on this platform compared to older Nissan-family vehicles. Some of the tools hobbyists use for older Nissan keys hit a wall here. The OBD port is the access point for enrollment, but the software has to speak the right protocol and retrieve the correct security credentials for that specific car before it can register a new key.

For add-a-key situations where you still have a working key, the process is a bit more direct. All-keys-lost takes longer because additional steps are involved in re-establishing security access. Either way, this is not a DIY job and there is no ignition-turn self-programming sequence on this system.

Question 4

My Q60 starts fine but the remote functions on the fob are intermittent. What causes that?

Accepted Answer

This one comes up a fair amount on Infiniti forums. If the blade starts the car without issue but the remote lock and unlock are flaky, the transponder side is working fine. The issue is on the RF side of the fob.

First thing to check: the battery contact inside the fob. On this style of key body, the contact pins can lose tension over time, especially if someone has popped the fob open before. Even a fresh battery sitting on a slightly bent contact will drop signal range or cut out entirely. Open the fob, check the pins, reseat the battery correctly.

If that doesn't do it, intermittent reception can also point to the vehicle's receiver or antenna circuit. That's a different diagnosis and a different fix, but rule out the fob side first before going there.

Question 5

I only have one key for my 2015 Q60. Should I get a spare made now or wait until there's a problem?

Accepted Answer

Get the spare now. All-keys-lost on a vehicle with this level of immobilizer security takes longer, costs more, and leaves you without the car until it's resolved. Having one working key in hand when a second is made is a faster and simpler job.

One key also means one lost moment or one dead fob turns into a real problem. Mobile service in Fire Mountain means I come to you, but it's a better call to make before you're stranded.
