🔧 PRO TIP
The 2004 Lexus IS300 runs a Texas Instruments 4D-68 transponder chip paired to the immobilizer ECU (part 89780-53310 on most IS sedans). The key is a remote head style, FCC ID HYQ1512V, with a TOY48 blade, not TOY43. That blade distinction matters because a wrong blank won't even slide into the cylinder. Battery is a CR1616, and when it gets weak the remote range drops to about two feet before the buttons quit entirely. Swap the CR1616 first before assuming the worst.

2004 Lexus IS Remote Head Key Replacement - Fast, Affordable & Professional

Got a call from a guy near Arroyo Vista Community Park in Moorpark. He had a 2004 Lexus IS300 and wanted a spare key, not because anything was broken, but because he only had one and his wife had been asking him to get a backup for months. He finally caved during the holidays while visiting his parents.

He asked me straight up whether an aftermarket key would hold up the same as a dealer one. Fair question.

I showed him the blank I carry. Same TOY48 blade profile, same 4D-68 transponder chip, same three-button remote head layout matching his HYQ1512V. The housing has the same weight and button feel. Only difference is no Lexus logo stamped on the back. He turned it over in his hand a couple times like he was looking for the catch.

Cut the blade on site, then programmed the 4D-68 chip through the OBD-II port using the existing master key registration procedure. The IS300 immobilizer ECU accepts up to four transponder key IDs, so adding a second was quick. Tested the remote lock, unlock, and trunk. Tested the transponder start three times cold.

He clicked both keys side by side, feeling the buttons. Same travel, same click. He just nodded and said his wife would be happy.

The whole job took about twenty minutes and cost him a fraction of what the dealer wanted for their version of the same key.

“My Chevy key snapped while I was running errands in North Oxnard. He removed the broken piece from the ignition, cut a new blade, programmed the transponder, and tested everything thoroughly. The whole job was smooth and professional. Best automotive locksmith I have used.”

“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.”

Lexus IS Mobile Service FAQ

Real costs, no dealer surprises

What is the best way to handle all-keys-lost on my 2004 Lexus IS300?
Call a mobile locksmith before you call the dealer. The Lexus dealer route for an all-keys-lost IS300 means towing the car in, waiting for parts, and paying their shop rate on top of key cost. Some owners on ClubLexus have reported multi-day waits just for the dealer to schedule the work. I come to you, reset the immobilizer ECU (89780-53310), cut a new TOY48 blade to code, program the 4D-68 chip on site, and hand you working keys the same day. The price I quote on the phone is the price you pay. No tow bill, no surprise labor line items.
Can you delete lost or stolen keys from my 2004 Lexus IS so they can't start it?
Does my 2004 Lexus IS key have a hidden emergency blade inside?
