Single Button KeyFob - Red or Blue Board

[Disc300Series]

Does anyone know if a replacement single button keyfob with a red board inside will work on an alarm that previously used a blue board keyfob for a Discovery Series 1 300 Tdi..?? Cheers.

Open the bonnet and ask the assistant to hold down the bonnet switch. Either get into the car and close the door, or wind down the window and stand outside.

NOTE: If you vehicle is fitted with a separate immobiliser, switch it off - as if you were going to drive the vehicle.

Instructions 1 to 7 must be done within 8 seconds!

1) Switch ignition ON
2) Switch ignition OFF
3) Lock doors - using sill button (press down)
4) Unlock doors - using sill button (pull up)
5) Release bonnet switch
6) Switch ignition ON
7) Switch ignition OFF

If the alarm is correctly accessed, the horn will sound and the red alarm LED will light and stay on. It is now possible to programme the key fob(s).

NOTE: A maximum of 2 key fobs can be programmed.

Carry out instructions 8 - 10 within 2 minutes.

8) Press and HOLD down button on the first key fob until the alarm LED flashes a few times
9) repeat instruction 8 for the second key fob
10) The alarm LED will go out if both key fobs have been installed correctly

NOTE: If only one key fob is programmed, after instruction 8 turn the ignition ON and OFF to finalise the programming.

Hi,

I purchased a replacement off ebay, turned out I got the wrong mhz.

Both boards are red, so colour of the boards is completely irrellivent.

You need to find the alarm ECU, it should have a sticker on it saying what the MHz is - 418 MHz or 433 MHz from memory. Mine was under the driver side dash where the fuses are just inside to the right, but mine's a '94 200Tdi.
