Central Locking Key

[MBA-Supra11]

Hello, How do I programme a new central locking key to my car? Just wondering if it can be done or not. Thanks

I have an idea ( after a few Crimbo drinks ), how about programming to a universal tv remote and have the key cut then transfer one to the other. How cool would that be

Obtain all remote transmitters for this vehicle.

 

1. Insert key into ignition and turn ignition switch to ON position.

 

2. Locate the ECU (Engine Control Unit) and press and hold the ECU PROGRAMMING button for 3 seconds. The ECU will be located under one of the front two seats, the trunk, or under the dashboard on the drivers' side. You will need a small pointy object like a pen to depress the ECU button. After pressing the ECU button for three seconds, you will see the STATUS MONITOR LED turn on for 5 seconds. Vehicle is now in programming mode.

 

3. Press and release either the top or bottom button on the remote (If you purchased a four button duplicate remote simply press the lock or unlock button since the other two buttons will not be used). The STATUS MONITOR LED will turn off. A chirp will be heard as well as one flash of the exterior lights.

 

4. Turn off the ignition. Programming is now complete, test remotes for proper programming.

 

You need to ensure the fob is at the correct frequency which for European cars post 1996 is 433MHz. A USA sourced fob will likely be 315MHz. I downloaded these instructions a while back to programme a second remote but an OEM one never came up on eBay at a price I could justify. So, if you try it and it works let us all know.

 

PS - the ECU is under the front seat...............

Thanks I will try it.

The above seems to relate to a car with a factory alarm. I say this as it goes on about the status monitor LED. The LED as far as I know was only installed with the factory alarm.
