Lexus RX400H & RX450H genuine 89904-48K10 proximity key - 312/314 MHz - 8A - electric tailgate 231451-0010 PCB

Genuine Lexus 3 button 89904-48K10 proximity key for use with hybrid models after 2015 where the circuit board number matches as shown in the photos.

Your original remote circuit board must have the number 231451-0010 printed on it.

The information int he table above is intended to be used as guide only. The best method to confirm if this key is suitable for your vehicle is to either check the part number using your VIN via the dealer or open the remote and confirm the circuit board has 231451-0010 printed on it.

The specific frequency of each button on the remote is vital here. This key transmits as follows:

LOCK: 314.00 MHz FSK

UNLOCK: 312.50 MHz FSK

TAILGATE: 314.00 MHz FSK

This specific part is designed for the Hybrid model and features the blue line in the logo on the back of the key.

A similar circuit board may also have been used with non hybrid models such as the RX200T & RX350 but you will need to supply the VIn for your vehicle so we can confirm the correct key for it as the frequency of each button is different and if you choose the wrong key it will not work on your vehicle.

Please take care when opening the case of your proximity key to not damage it. 

If you are not sure you can send us a photo of the front and back of the circuit board in your current smart key and we will assist you to identify the correct replacement.

This type of proximity key is also sometimes referred to as a smart key or prox key as it allows you to start the vehicle without having to put it in a slot or put a key in the ignition.

The battery is included in the price and if you need a spare you can order this under compatible items.

A suitable aftermarket emergency key blade is listed under compatible items as one is not included in the price.

Coding an extra key when you have a working key is not a problem, however if you loose your only smart key, then the cost and complexity of the process escalate dramatically. It is not uncommon for customers to be charged up to $3500 by the dealer to resolve the issue when all keys are lost. Having a spare key for your Toyota is essential if you want to avoid a very large bill and the prospect of being without your vehicle for up to 3 weeks.

This type of smart key can only be coded to your vehicle using specialist diagnostic tools by a licensed locksmith or vehicle repairer. We can code the smart key and cut your key in our workshop in East Victoria Park WA or you can have it done locally to where you live.

We charge $90 to code this type of smart key and cut the emergency key blade if we have supplied it. You will need to call to make an appointment.
