Lexus started using electrical keys in 1997. The first models to use this key was the LS400. Since 2000 most Lexus vehicles adopt the use of transponder keys.
In 2007 few models use keyless entry based on the Smart Key System. This technology used as either standard or optional equipment. In 2015 few models switched to a sidewinder encrypted keys.
The Lexus immobilizer is a state-of-the-art theft deterrent system. Research shows that immobilisers reduced the rate of car theft by 40%.
Lexus vehicles manufactured and delivered with 2 types of keys. A master key to operate all the locks and a valet key that cannot operate the glove box or trunk locks. Inside the vehile there is an immobiliser programmed to recognize it's specific keys. When the key inserted into the ignition, the transponder sends an RF signal to the engine immobilizer unit. The car will only start if the signal sent by the key matches the one stored in the immobilizer. If the immobiliser doesn't recognize the code, the immobilizer will lock down the engine.
The first generation Lexus transponders have a simple on-board procedure to duplicate keys if you have at least one master. The models and years who support on-board duplication and the process describes here. Later vehicles use an encrypted transponders and need to be plugged to diagnostic equipment.
If your Lexus made before 1998, your vehicle most likely use a TR-47 key with no chip. All you need to do is to find a dealer, locksmith or even a hardware store with a car key cutting machine. Then drive to them with one existing key or with the VIN and get it duplicated by copying the same key grooves.
If your Lexus that made after 1998, your vehicle might use an TOY43 transponder key.
This first generation Lexus transponder keys is duplicated by an on-board cloning process. The process describes here
Cloning TOY43 key requires proper programming tools. A locksmith or the dealer can cut and clone a duplicate key. The vihicle and a functional master key must be present on-site.
Duplication by VIN is usually done when the blade is dent or damaged but the chip is intact. Having the VIN, the dealer or a locksmith will get the key-code cuts from Lexus. This process requires appropriate diagnostic equipment and programmer, license, a proof of owneship and the vehicle present.
Lexus models decked with TOY44 keys have no provision to reproduce keys on-board. To get a surplus keys, driver can use cloning or duplication by VIN. This done by the dealer or a licensed locksmith. a precise diagnostic equipment and programmer required and all previous keys are present.
If you lost all your keys to a Lexus that made before 1998, your vehicle most likely use a TR-47 key with no chip. All you need to do is to go to the dealer or to a locksmith store with the VIN and ask him to make you a new key.
This process is quite simple and should cost less than a 100$ in most cases.
One exception to the above is if the ignition changed and is not in sync with the VIN.
In the second case a locksmith need to replace the ignition again or to make a new key by reading the key grooves inside the ignition cylinder. This procedure is more complex and requires a locksmith with the right machine and experience.
The first years of Lexus transponder based vehicles had no interface to deal with a lost key. Even if the owner left with only a valet key.
* A valet key will start the car, but not the trunk and glove-box.
If all the master-keys are lost, the dealer/factory procedure is to replace the motor vehicle main computer (immobilizer module). This will cost around $2,000.00. Since keys are lost and stolen on a daily base, this design proved senseless.
After Lexus got some bad publicity on a multi-national level. The key problem eventually led them to initiates a free computer replacement program. When ever this situation occurs, owner will only pay for labor charges. The solution reduce the price to $1,200.00-$1,500.00 but the program only applies to certain owners.
After losing so many keys and the waste of so much money. A method developed to help vehicle owners save money when this situation occurs.
Specialized technology called ECU reflash now allows certain locksmith technicians to erase the key-data stored in the vehicle immobilizer. Then program new key-data to the car. Okey DoKey Locksmith have the manifold equipment to performs this process.
If you lost all your keys to a vehicle that uses TOY44 key, the ECU reprogrammed to accept a new key and reject the old one. This comes as a security measurement certifying the disabling of the old/lost/stolen key.
This re-coding interface available only to the Lexus dealer or to a licensed locksmith. This means that the car towed to the dealer or a mobile locksmith will have to come out to the site of where the car is at.
