Question 1

What is the cheapest way to handle all-keys-lost on my 2017 Infiniti Q70?

Accepted Answer

Call a mobile locksmith instead of going to the dealer and arranging a tow. All-keys-lost on the Q70 means no fob is enrolled, so the car won't start, but that doesn't mean you need a flatbed. I come to the vehicle, connect to the diagnostic port, read the security data, and enroll fresh keys on site. The old fobs get wiped in the same process, so anything lost or missing can't start the car afterward.

Dealer pricing on this job is steep, and that's before tow fees. My price is a fraction of that, and the job gets done in your driveway or parking lot. If you're in the East Valley area of Escondido, same-day service is usually available. While we're there, getting two keys done in one session is always smarter than one, so you're never back in this situation.

Question 2

Can you delete a lost or stolen fob from my Q70 so it can't start the car anymore?

Accepted Answer

Yes, and it's worth doing immediately if a fob went missing or was stolen. The way the Q70's key registration works, the system holds a list of enrolled fobs. When we reprogram, we can clear that list entirely and only re-register the fobs physically present during the session. Any fob not in that room stops working. It won't unlock the doors, won't communicate with the immobilizer, and won't start the car.

This is the same procedure used for all-keys-lost, just applied with security in mind rather than convenience. If you still have one working key, we don't have to wipe everything. We can add a new fob and leave yours enrolled. But if a stolen fob is the concern, a full re-registration that excludes it is the cleaner call.

Question 3

Does my Q70 Intelligent Key have a hidden emergency blade inside it?

Accepted Answer

It does. There's a small mechanical release on the fob housing. Press it and the blade slides out. That blade fits the lock cylinder on the driver door, which on the Q70 is tucked behind a small cover on the door handle pull area. Pop the cover off, insert the blade, and you can manually unlock the door even if the battery is completely dead or the smart key system isn't responding.

One thing to note: getting inside is the easy part. If the fob battery is dead and you can't get the push-button start to recognize the fob at all, there's a backup position for holding the fob near the start button that some owners don't know about. It doesn't always work if the battery is truly gone, but it's worth trying before assuming the fob itself has failed.

Question 4

I bought a replacement fob online for my Q70. Can I program it myself or do I need a locksmith?

Accepted Answer

You need a locksmith or a shop with the right diagnostic equipment. There is no DIY programming sequence for the Q70 smart key. No ignition turns, no button combinations, no onboard relearn. The fob has to be enrolled through the OBD port using professional tools that can communicate with the vehicle's security system. If the fob shell and electronics match the factory ID for your vehicle, it can be paired. If it doesn't match, it can't be enrolled regardless of what the listing said. Bring the fob you bought and I can confirm whether it's compatible before committing to the job.

Question 5

The push-button start on my Q70 is hit or miss. Sometimes it works, sometimes it just flashes and does nothing. Is the fob dying?

Accepted Answer

That intermittent behavior is one of the more common Q70 owner complaints, and a weak fob battery is the most frequent cause. A CR2032 that reads as "not dead" on a basic tester can still drop enough voltage under load that the start button loses confidence in the signal. Swap the battery first.

If a fresh CR2032 doesn't fix it, the next suspects are the battery contact clips inside the fob housing, especially if the fob was ever pried open instead of released properly. A bent clip gives intermittent contact that mimics a dying fob almost perfectly.

If the fob checks out and the problem continues, that points away from the key itself and toward something on the vehicle side, like the antenna that reads the fob near the start button. That's a different diagnostic, but I can sort that on site too.
