🔧 PRO TIP
The 2004 4Runner uses a transponder key that has to be registered to the immobilizer before the engine will run. The key blade gets cut to the vehicle, then the chip inside gets enrolled through the OBD port. One thing that trips people up: if someone hands you a key that was previously programmed to a different Toyota, the chip may already be locked to that other vehicle's system and cannot be re-enrolled. Always start with a fresh, unprogrammed key blank. Also worth knowing - the 2004 system has a finite number of key slots, so if you're adding a spare rather than replacing a lost key, confirm how many slots are already occupied before you start. And if the engine cranks but dies after two seconds, that's the immobilizer rejecting the key, not a starter or fuel problem. Don't let anyone replace the starter before they've ruled out the key.

2004 Toyota 4runner Transponder Key Replacement - Fast, Affordable & Professional

A woman in North Park called me about her 2004 4Runner. It had been starting fine for about ten days after another locksmith cut and programmed a replacement key, and then it started acting up. Mornings were fine. By evening, nothing. Crank, run for two seconds, die. She was convinced something was wrong with the wiring or the fuel system.

I drove out to her spot near the laundromat off 30th. She showed me the key - visually it looked right. But I plugged in and read the chip, and the transponder that had been used was the wrong generation for this vehicle. The 2004 4Runner's immobilizer is not forgiving about that. What happens sometimes with a mismatched chip is it passes the initial enrollment check but fails the deeper rolling verification the system runs over several drive cycles. So the truck starts, the owner thinks the job is done, and a week later they're stranded.

I programmed a correct, generation-matched transponder key on site. Tested it through several start cycles before I left. She asked me what the other locksmith had charged her. I told her what I charge. She did the math out loud.

The difference between a key that works and one that works for a week is matching the right chip to the right system. That's not a shortcut I take.

“They responded instantly, showed up within an hour, and arrived exactly when they said they would. Made a copy and programmed a fob for my 2014 car with a worn ignition in about 15 minutes. The new key works perfectly and feels like a dealer key.”

Toyota 4runner Mobile Service FAQ

Real costs, no dealer surprises

What is the cheapest way to handle all-keys-lost on my 2004 4Runner?
Call a mobile locksmith before you call the dealer or a tow truck. All-keys-lost on a 2004 4Runner means the immobilizer has to be reset, a new key blade has to be cut to your locks, and the fresh transponder has to be enrolled to the vehicle. Dealers will do all of that, but you're looking at a tow to get it there, potentially a day or more wait, and a bill that reflects their overhead. I come to your location in San Diego - North Park, wherever the truck is sitting - bring the equipment to do the reset and programming on site, and cut the key to your vehicle right there. No tow, no overnight, no waiting room. Call for pricing, but the savings over the dealer route are real.
Can you wipe lost or stolen keys from my 4Runner so they can't start it anymore?
My 2004 4Runner is a transponder key vehicle - is there any emergency backup if I lose my only key?
The engine cranks and starts but shuts off after a couple of seconds. Is that the transponder or something else?
Can I program a second key to my 2004 4Runner myself, or do I need a tech with equipment?
