A: The answer below is a short explanation. For a more detailed explanation and GREAT TIPS on how to save money, please visit our blog post: Car keys replacement cost
In short, to replace a Lexus LX key can cost between $230-$320. It depends on a few factors:
- Type of key
- The year manufactured
- Time of day & your location
- Where you get a key replacement (dealer, automotive locksmith, online, etc.)
- Availability of code to cut a new key
- Original ignition or not
The type of key you had and the year the car was manufactured are maybe the most important factors (chip, intelligent fob, “push to start”, remote, regular “non-transponder” key). The newer the car is, the better security features the key had and therefore you can expect to pay more than $250 for a replacement key.

In addition, it depends on where you get a key replacement. The dealer, automotive locksmith or get it online. Click here to get a more detailed explanation of how to get a replacement key.
The dealer usually charges about 10%-15% less than a locksmith would for the key. However, most chances you will have to tow the car there to program the new key or remote and therefore the total price is usually higher.
Furthermore, consider that if you are looking to have a locksmith to come out and make you a new key outside regular business hours, the price may go up.
Finally, in case your ignition cylinder was changed before (usually with older cars), that probably means that the code for the key may not be useful and the key will have to be either cut manually by a locksmith or to change the ignition again which in this case the dealer can’t be of help.
Q: Can I get a Lexus LX key replacement by VIN?
A: That depends on the year of your model and the type of key you had.
The VIN allows the dealer or automotive locksmith access to the key code on file, i.e. they can cut you a replacement key by code which makes the process very fast and easy. You must, however, consider two things:
- For Lexus models that are older than 10 years: There are no codes available. Therefore, an automotive locksmith is your only option to get a replacement key.
- For Lexus LX vehicles that are equipped with a transponder system and/or remote/ intelligent key/ fob key: Codes are available. However, programming is necessary and therefore you will have to either tow the car to the dealer or have an automotive locksmith come and program the key on site.
Q: Lexus LX key programming – which keys you can program yourself, which keys require programming tools & more
A: The Lexus has different types of keys. Some require programming and some do not. All transponder chip keys and/or smart key fobs need to be programmed with a special programming machine that only an automotive locksmith or the dealer has. There is no need to program non-transponder metal keys.
To keep things simple, we divide all Lexus keys into two categories:
- No programming needed (Non-transponder keys)
- Keys that need to be programmed, which means you will need an automotive locksmith or the dealer (transponder or remote keys)
No Programming needed:
Lexus LX non-transponder keys are metal keys that have no chip in them and therefore no programming is needed:
None – The Lexus LX key has a chip and needs to be programmed.
Lexus LX keys that need to be programmed and you will need an automotive locksmith or the dealer:
Keys in this category, such as remote smart keys, intelligent keys or key fobs, as well as transponder keys, have a security chip in them, which requires programming. A special machine is needed to program them and so you will need an automotive locksmith or dealer to do it for you (Usually for models manufactured after 1998).
Keyless entry information for the Lexus LX:
2019-2020: There is a built-in keyless entry in the remote key.
