Lexus Key Replacement in Milwaukee

Lexus keys for the RX, ES, IS, NX, and GX

Lexus key replacement in Milwaukee is mostly smart key work. The RX and the ES are the Lexus models we see most, followed by the IS, the NX, the GX, and the newer UX, with an older LS, GS, or LX now and then. Lexus is Toyota's luxury brand, and under the leather its keys come from the same families of chips and smart keys as a Toyota's. That is good news for you: the parts are known, and we program them at the car.

Smart access with push-button start

Lexus calls its keyless system smart access with push-button start. With the key in your pocket or bag, touching the door handle unlocks the car, and the ENGINE START STOP button starts it. Lexus spread this system across its models from the mid-2000s, and most Lexus models on the road today use it. Each Lexus smart key holds a metal emergency key for the driver's door, released by a small button on the key.

When the key battery dies

A Lexus smart key needs its battery to be found in your pocket, but not to start the car. When the battery is weak, the owner's manual has you hold the Lexus emblem side of the key against the ENGINE START STOP button with your foot on the brake; the car reads the key's chip at close range, a buzzer sounds, and the button then starts the engine.

The dead-battery start also tells you what to ask us for. If your Lexus starts with the key held against the button but not with the key in your pocket, the key needs a battery, not a replacement. If it does not start even with the key against the button, the key itself has a problem, or it was not programmed to this car, and that is a job for us.

Spare Lexus keys

With one working key, a spare Lexus smart key starts at $159, and a spare chip key for an older Lexus starts at $69 (spare car key). We bring a key that matches your model's smart key type, program it through the diagnostic port, and cut the emergency key at the car. Count on 15 to 60 minutes. Lexus models leave the factory with two smart keys, and a used Lexus that came with one key is a common reason for a call (smart keys).

All Lexus keys lost

With no key left, we open the car first (car lockout). On many Lexus models from about 2017 on, including the NX, the IS, the newer ES, and the UX, making a smart key with no working key means connecting our tool to the smart key module behind the dash and running an online calculation, so the visit takes longer than a spare. On older models, the new keys are programmed through the diagnostic port. After the session, the lost keys no longer start the car. All keys lost starts at $119 for a chip key, and smart keys cost more (lost car keys).

Older Lexus models with a turning key

Lexus models from the 1990s and early 2000s, like an early RX 300 or a GX 470, use a turning key with a chip in the head, and many came with a separate valet key, also called a sub key, that starts the car but does not open the glove box, or the trunk on a sedan. If the valet key is the only one you have left, tell us when you write, because it changes how the new key is programmed. Remotes for older Lexus models with a turning key are programmed from $119 (key fobs).

Toyota shares the same chip and smart key rules; see Toyota keys. For a German luxury car, see BMW keys, and for every make, car keys by make.
