🔧 PRO TIP
The 2004 Lexus LS was genuinely early to the smart key game, and the system on these has a quirk worth knowing: a completely dead fob battery can knock out the backup start routine if the fob never gets close enough to the start button area for the passive coil to read it. So the car sits there looking fully dead even though the keys are still registered in the system. Swap the CR1632 first, hold the fob flat against the start button area, and give it a second. A lot of these "totally dead" calls turn out to be that one move away from a normal start. If the battery swap clears it, clean the battery contacts while you're in there. These fobs are old enough that the clips have had twenty years to get lazy. All-keys-lost on this generation is a different story. The immobilizer has a timed relearn window built in, and you cannot shortcut it. Once diagnostic equipment initiates the process, you wait out the countdown before the system will accept new key registration. Plan for the on-car portion to run closer to thirty minutes on an all-keys-lost job.

2004 Lexus LS Smart Key Replacement - Fast, Affordable & Professional

He'd parked in the premium lot at the airport and been gone about a week on a business trip. Came back, walked up to the car, pressed the fob. Nothing. Held it right against the start button like he'd seen someone do once. Still nothing. The fob battery had gone flat while the car sat, and the backup coil wasn't picking up enough signal to do anything useful.

Dealer's first available slot was Thursday. It was Tuesday afternoon.

He found EZ Car Keyz while he was still standing in the lot, luggage at his feet, trying to figure out whether a tow made any sense. I was there in Old Town National City within about 35 minutes.

I got the door open, connected my diagnostic equipment, and pulled up the key registration status. The keys were still enrolled in the system. The dead battery had triggered a communication fault that the passive backup routine couldn't push through on its own. Swapped in a fresh CR1632, cleared the fault, confirmed the fob was reading correctly at the start button, and walked every function: door lock, door unlock, trunk release, alarm. All good.

He was on the road in under twenty-five minutes from when I pulled up. The dealer visit would have meant two days in a queue, and that's before factoring in getting the car there.

Lexus LS Mobile Service FAQ

Real costs, no dealer surprises

How long does a 2004 Lexus LS key replacement take?
Depends on the situation. If you have at least one working key and just need a spare added, the programming side is relatively quick once I'm connected. If all keys are lost, the immobilizer on this generation has a timed countdown built into the relearn process. Once the equipment initiates it, you wait the system out before it will accept new key enrollment. That puts the all-keys-lost job at roughly 25 to 35 minutes of on-car time. Either way, start to finish including testing every function, most visits wrap up well under an hour.
