🔧 PRO TIP
The 2003 Sequoia runs a key-and-remote setup, not a smart key. You have a separate transponder key that starts the car and a remote fob that handles the locks. Two different jobs if either one fails. The fob takes a CR2032 and handles lock, unlock, panic, and the rear hatch glass. The transponder key handles the ignition. If the fob buttons go weak or dead, swap the battery first, but that has zero effect on starting the car. If the engine starts and immediately stalls, that is the immobilizer talking, not the fob. Those are two separate problems and people mix them up constantly on these.

2003 Toyota Sequoia Remote Replacement - Fast, Affordable & Professional

She was at a sushi restaurant in Otay Mesa, over near Ocean View Hills, when her bag got taken off the chair next to her. Car keys, wallet, phone, all of it. She borrowed the server's phone, called the police, called her husband, then called me.

Her 2003 Toyota Sequoia was sitting in the parking lot with zero keys.

Her husband had already called the dealer while she was waiting. The answer was three to five business days, the vehicle needed to be towed to the service department, and they were recommending a full rekey. The estimate he got over the phone was not a small number.

I got there that evening. The first thing I walked him through on the phone, before I even left, was the difference between adding a spare key and all-keys-lost. When you add a spare, the car already trusts one working key and you are just registering another. All-keys-lost means the stolen key or fob is still out there, so I wipe the key memory completely and start fresh. The old fob becomes useless to the immobilizer the moment that process is done. It can still physically fit the door, but the car will not fire. That is the part people most need to hear when something gets stolen.

I decoded the lock on site, cut two new keys, and registered both the transponder keys and the remote fobs using my scan tool. Done before the police report was finished.

She drove home that night with two working keys. The dealer route would have meant a tow, a multi-day wait, and spending a lot more. The stolen key is dead to that Sequoia now. That is the job.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”

“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”

Toyota Sequoia Mobile Service FAQ

Real costs, no dealer surprises

How much does a 2003 Toyota Sequoia key replacement cost?
Call us for exact pricing, but it will be a fraction of what the dealer quoted you. The dealer tends to break this into separate line items: the fob, the key blank, a cutting fee, programming labor, and sometimes a diagnostic charge just to pull the immobilizer data. We do it as one price, at your location, and that covers the key blank, cutting to your vehicle, programming the transponder, syncing the remote, and testing everything before we leave. No surprises when you get the invoice.
Is a mobile locksmith actually cheaper than the Toyota dealer for this?
Does the price include cutting and programming?
My 2003 Sequoia starts fine but the remote fob stopped locking and unlocking the doors. Do I need a new fob?
I bought a replacement fob online for my 2003 Sequoia. Can I program it myself?
