Question 1

Do you use OEM or aftermarket keys for the 2015 Quest?

Accepted Answer

We supply quality blanks that are verified to match this vehicle's Intelligent Key system, not random pulls from a bulk bin. On the Quest specifically, the fob has to support the sliding door and liftgate functions in addition to the standard lock, unlock, and start buttons. Cheap aftermarket units sourced from auction sites sometimes skip or mismap those extra buttons, and you don't find out until you're standing next to the van with the door not responding.

Nissan dealers will typically refuse to program a third-party fob brought in from outside, and there's a practical reason for that beyond policy. We carry blanks we've tested and stand behind. Same goes for the emergency insert blade that lives inside the fob housing. If the blank cuts soft or the transponder chip inside doesn't communicate cleanly with the immobilizer, the key is going to cause headaches. We match the right blank to your vehicle before we leave for your location.

Question 2

How long will a replacement key last on a 2015 Quest?

Accepted Answer

A properly programmed key should last as long as your original. The programming itself doesn't wear out. What does fail over time is the CR2032 battery and occasionally the contact clips that hold it. Quest owners on Nissan forums have noted that the battery contacts in this fob style can develop a slight corrosion or bend that causes intermittent behavior before total failure. If your fob starts acting inconsistent, clean the contacts before assuming the key needs replacement.

If the fob shell cracks from being dropped, the electronics can often be transferred into a new housing for much less than a full replacement key. That's a repair worth asking about before buying a whole new unit.

Question 3

What if my new key stops working a few weeks after you program it?

Accepted Answer

Call us and we come back. Every key we make is covered under warranty.

The failure mode that shows up most on Quest forums is a key-not-detected warning on the dash even when the fob still locks and unlocks the doors. That split behavior, remote functions working but start not responding, usually points to the immobilizer side of the system rather than the fob itself. It could be a weak battery, a registration issue, or the antenna loop around the start button losing contact. We diagnose it either way. If it's something we programmed, we fix it. If it turns out to be a vehicle-side issue, we tell you exactly what you're dealing with before you spend money at the dealer.

Question 4

I lost all keys to my 2015 Quest. Can you still make a replacement?

Accepted Answer

Yes, all-keys-lost is a standard job. It takes longer than add-a-key because the vehicle's key memory has to be cleared and the new fob registered from scratch. There's a timed sequence built into that process on the Intelligent Key system, so the appointment runs longer than a simple spare, but it's fully doable on site. Bring your title or registration and a photo ID confirming ownership. That paperwork is required before we start on any all-keys-lost job, no exceptions. Once the new key is registered, any previously lost fobs are wiped from the system and can no longer start the van.

Question 5

My Quest shows a key warning on the dash but the fob battery is new. What's going on?

Accepted Answer

This one comes up a lot on Quest owner forums, and a fresh battery doesn't always fix it. A few things to check: make sure the CR2032 is seated flat and the contacts aren't slightly bent from a previous swap. Beyond that, if the warning appears only in certain spots, like a parking garage or near certain store entrances, interference from other signals can temporarily confuse the system and it clears on its own.

If the warning is persistent and the van won't start, hold the fob directly against the start button when you press it. That's a backup method built into the system for when the key's signal is too weak to be read at normal range. If the engine fires that way but not otherwise, the fob's transmitter is weakening and the key needs attention. If the van won't start even with direct contact, that points to a registration or immobilizer issue rather than the battery, and that's when you call us.
