Furthermore,
consider that if you have a locksmith come out and make you a new key outside regular business hours, the price may increase.
Finally,
If you have previously had your ignition cylinder replaced, which is quite common in older cars, this probably means that the code for the key may not be useful. In such cases, the key will have to be cut manually by a locksmith, or you will have to change the ignition again, and here the dealer can’t help.

Q: Can I get a Lexus SC300 key replacement by its VIN?
A: That depends on the year of manufacture of your car and the type of key you had.
The VIN gives dealers or automotive locksmiths the option of accessing the key code on file – i.e., to cut you a replacement key by code which makes the process fast and easy. There are however two things to consider:
- If your vehicle is older than 10 years, Lexus dealers will no longer have its key code record, so an automotive locksmith will be your only option to get a replacement key.
- For vehicles equipped with a transponder system and/or a remote/intelligent key/fob key, the codes should be available. However, as coding is required, you will have to either tow the car to the dealer, or have an automotive locksmith come and code the key on site.
