FAQ:

 

Q: I lost my Lexus LS400 car keys, have no spare, and need a replacement. How and where can I get a replacement key?

 

Generally speaking, you have three options:

  1. Call an automotive locksmith that offers a mobile service for Lexus LS400 cars. We can help you with that.
  2. Tow the car to the dealer.
  3. Order a key online and have the dealer or locksmith cut and program it for you (if necessary).

A word of caution: The type of key you need depends on the year and model of your Lexus LS400. Therefore, the options for getting a new key made and programmed depend on whether you need a remote, an intelligent fob, push to start button, a transponder, or a regular key.

Q: What should I tell the locksmith or dealer when I call for service?

A: First, make sure you have the exact year, make, and model, e.g., 2006 Lexus LS400.

Also, write down the VIN (Vehicle Identification Number) of the car located on the left side of the dashboard near the mirror (Click here for more information). The VIN helps the locksmith or dealer verify the year, make, and model of the car and determine which key you had.

Finally, make sure you can show ownership of the car by having the necessary documents – title, ID, insurance card, etc.

Q: Lexus LS400 key replacement cost – How much does it cost to replace a Lexus LS400 key without the original? What is the average price?

Lexus LS400 key replacement cost - Estimate only

Lexus LS400 key replacement cost – Estimate only

 

In short, replacing a Lexus LS400 key can cost between $60 to $240. The cost depends on a few factors:

  1. Type of key
  2. The year manufactured
  3. Time of day & your location
  4. Where you get a key replacement (dealer, automotive locksmith, online, etc.)
  5. Availability of code to cut a new key
  6. Original ignition or not

The type of key you had and the year the car was manufactured are the most important factors (chip, intelligent fob, “push to start”, remote, regular “non-transponder” key). The newer the car is, the better the security features the key has. Therefore, you can expect to pay more than $250 for a replacement key. Click here to see the model and type of key you had for a more accurate price and additional information.

Also,

the price depends on where you get a key replacement. Did your replacement key come from the dealer, or an automotive locksmith? Or did you get it online? Click here to get a more detailed explanation of how to get a replacement key.

The dealer usually charges about 10% to 15% less for the replacement key than a locksmith would charge. However, you will likely have to tow the car there to program the new key or remote key fob. Therefore, the total price is usually higher.

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,

in case your ignition cylinder has been changed, which is quite common in older cars, that probably means that the code for the key may not be useful. In these instances, the key will have to be cut manually by a locksmith, or you will have to change the ignition again, which in this case, the dealer can’t help.

Q: Can I get a Lexus LS400 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. For vehicles older than 10 years: Lexus dealers don’t keep a record for vehicles older than 10 years. An automotive locksmith is therefore your only option to get a replacement key.
  2. For vehicles equipped with a transponder system and/or a remote/intelligent key/fob key: Codes are 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.

Q: Lexus LS400 key programming – Which keys can you program yourself? Which keys require a programming tool? & more

A: Lexus LS400 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.

To make things simple, we divided all Lexus keys into two categories:

  1. No programming needed (Non-transponder keys).
  2. Keys that need to be programmed (Transponder or remote key fobs). These keys required the expertise of an automotive locksmith or the dealer.

 

No Programming needed:

Lexus LS400 non-transponder keys are metal keys that have no chip in them. Therefore, no programming is needed.

Lexus LS400 keys that need to be programmed – You will need an automotive locksmith or the dealer:

These keys, also known as remote smart keys, intelligent keys or key fobs, and transponder keys, have a security chip. Programming is needed. Also, a special machine is needed to program them. An automotive locksmith or dealer should do it for you. This process must be followed for most models made after 1998.

Q: I have a Lexus LS400 key and would like to get a keyless entry system to unlock all doors as well. Can you tell me which one should I get? Will it need to be programmed and can I program it myself or not?

A: Lexus LS400 has one keyless entry system option. For newer models, the key you have contains a built-in keyless entry system (a remote master key or key fob/smart key). Some need to be programmed by a professional locksmith or dealer and some don’t. Below you will find all the information relevant for Lexus LS400 entry system.
