🔧 PRO TIP
The 2004 4Runner uses Toyota's 4C transponder chip with a fixed-code immobilizer, not the newer 4D or smart key setup. The remote side (part number 89742-35021, FCC ID GQ43VT20T for three-button models) is a separate RF unit from the transponder. If your remote dies after a battery swap, the immobilizer still sees the key fine. You just lost the RF pairing. A quick remote relearn procedure through the driver's door lock cylinder fixes it. No scan tool needed for that part.

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

Out near Refugio State Beach in Santa Barbara, a guy flagged me down at the AutoZone parking lot. He had a 2004 4Runner with a key that barely worked. Remote was dead, engine start was hit or miss.

Turns out he had already called another locksmith. One of those $49 phone quotes that somehow became hundreds once the guy was standing at the car. The replacement key they gave him had intermittent start issues and the three remote buttons did nothing. Classic bait and switch shop, no license number on the invoice, no company name that traces back to anything real.

He found EZ Car Keyz through Google Guaranteed and his first question was how to tell a legit locksmith from a scam. I gave him my BSIS license number, LCO 6792. California Bureau of Security and Investigative Services. Background checked, insured, registered business. He looked it up on his phone while I worked.

I pulled out my Smart Pro, connected to the OBD-II port, and ran the full security handshake with the 4C immobilizer. Registered the transponder properly, then ran the remote relearn for the GQ43VT20T through the door lock cycle. All three buttons came back. Clean engine start every turn.

He kept the old junk key as a reminder. I keep my NASTF certification, my state license, and my YouTube channel with real Toyota jobs on camera. All verifiable before I ever show up.

“My car keys were stolen on a cold evening and Nick drove all the way out to Santa Barbara. He got into my car, made a new key, and charged $100 less than another company. Friendly, skilled, trustworthy, and genuinely caring. Nick is a hero.”

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Toyota 4runner Mobile Service FAQ

Real costs, no dealer surprises

My key broke off in the ignition of my 2004 4Runner. Can you get it out?
Yes. Broken key extraction is a standard mobile call for us. I use extractor picks to pull the broken blade without scratching the wafers inside the ignition cylinder. Once it is out, I can cut a fresh TOY43 blade from the extracted piece or decode the lock directly. The 2004 4Runner key shell (part 89786-08020) is known for cracking because the housing relies on a single plastic peg holding the blade to the head. Toyota forum owners report snapping them repeatedly, especially in cold weather or when the steering lock binds. If the 4C transponder chip inside the head is still intact, I transplant it into a new shell and skip a full reprogram.
What kind of transponder key does a 2004 Toyota 4Runner use?
My 2004 4Runner turns over but will not start. Could it be the key?
Can I program a new transponder key for my 2004 4Runner myself?
My 4Runner remote stopped working after I changed the battery. Is the fob broken?
