Furthermore,

consider that if you have a locksmith come out and make you a new key outside regular business hours, the price may increase.

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.

Lexus IS300 key fobs replacement

Lexus IS300 key fobs replacement

Very often when people get a replacement key fob, there are certain things they forget to check and ask the dealer or locksmith.

 

We gathered here the most relevant information and tips to make sure you won’t face a problem down the road.

First,

Make sure to get the key code of your Lexus IS300 key fob – Every key fob, has a unique code which locksmiths and dealers use to know the exact cuts to match your ignition, door and trunk cylinders.

Ask and keep your key code in a safe place

Ask and keep your key code in a safe place

Obviously, this code is different from one car to another. This key code costs money, and before the locksmith or dealer cut you a new key fob, they must pay to get the code from the Lexus database, which may cost them up to $100. Make sure you write down this key code and keep it in a safe place. In case you lose your Lexus IS300 key fob again in the future, it will cost you less to get a replacement, and the process will be faster.

Q: Can I get a Lexus IS300 key replacement by its VIN?

Lexus IS300 key replacement by VIN

Lexus IS300 key replacement by 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:

  1. 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.
  2. 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.

A: Lexus has different types of keys. Some require programming, and some don’t. All transponder chip keys and/or smart key fobs need to be programmed. This process requires a special programming machine that only an automotive locksmith or the dealer has. There is no need to program non-transponder metal keys.
