Question 1

I lost all my keys to my 2004 Nissan Armada. Can you still make a new one?

Accepted Answer

Yes, all-keys-lost on the 2004 Armada is a job I handle on site. The process involves reading the immobilizer data, clearing the existing key registrations, cutting a new remote-head key blade to your vehicle, and programming the transponder and remote functions from scratch. Any previously existing keys get wiped out of the system in the process, so if a lost key turns up later it won't start the car.

Nissan dealers typically ask you to tow a keyless vehicle to their service bay because they need it on their equipment. That adds a tow bill and a wait. I come to wherever the Armada is sitting, including Cardiff-by-the-Sea or anywhere else in Encinitas, and do the same work at your location for a fraction of what that dealer route costs.

Question 2

Do I have to tow my Armada to the dealer if I have no working keys?

Accepted Answer

No. The 2004 Armada is well within the range of what a properly equipped mobile locksmith can handle on location. Dealers tell people to tow because their workflow requires the vehicle in their bay. That's a dealer process problem, not a technical requirement.

I bring the tools to you. No tow, no scheduling around a service department, no leaving your vehicle somewhere overnight.

Question 3

How long does an all-keys-lost job take on a 2004 Armada?

Accepted Answer

On site, plan for roughly 45 minutes to an hour. There's a timed sequence built into the immobilizer reset on these, and you can't rush it. The blade also needs to be cut to the vehicle before programming, so both steps are happening together. It's not a 10-minute job if it's done right, but it's also not a full-day dealership ordeal. I do it parked in your driveway, your street, or wherever the truck happens to be sitting.

Question 4

My 2004 Armada starts fine but the remote buttons stopped working. Is the fob dead or is something wrong with the truck?

Accepted Answer

If the blade turns, the engine runs, and only the remote functions are gone, that points to the fob itself, not the vehicle. On the 2004 Armada remote-head key, the transponder chip that talks to the immobilizer and the remote transmitter that controls locks and panic are two separate systems inside the same housing. One can fail while the other keeps working.

First check: battery. These use a CR1620, which is a specific size. A CR2032 looks similar but won't seat correctly. If the battery is right and contact is solid but the remote still won't reach the doors from a normal distance, the fob may need to be re-paired to the vehicle. That's a quick procedure with the right tools. If re-pairing doesn't hold, the transmitter board inside the housing may have failed and a replacement fob is the next step.

Question 5

Can I buy a replacement fob online and program it myself for the 2004 Armada?

Accepted Answer

The remote function on these can sometimes be re-paired through an onboard procedure, but it depends on whether your existing key is already registered to the immobilizer or if you're starting with a completely fresh unprogrammed unit. The transponder side is the part that governs whether the engine will run, and that portion does require the right equipment to register correctly. If you buy a remote-head key online and it arrives uncut and unprogrammed, you're looking at needing both a key cut and a transponder enrollment before it will start the car. Buying the part is fine. Just know you'll still need someone with tools to finish the job.
