Mondeo Keys

[mondeo_man]

Morning all,

I have picked up a mk2 Mondeo on a 99 plate.

I received x2 keys, both key fobs with 3 buttons. One works in the doors and starts the engine, the other just opens the doors manually.

Doesnt work via the buttons, have tried the old Switch ignition to 0 to ll position 4 times. LED for immobiliser stays on so I presume is now in learning mode. Press buttons on fob and nothing at all happens. Have tried putting in a new battery. Key also doesnt start the engine, I dont think the chip inside the key is programmed to the immobiliser. Is there anyway to do this DIY ?

Any ideas why the keyfob isnt working ? Thanks in advance.

IIRC to pair a new imob chip you need 2 working keys/chips to access programming mode
it works as follows

• Insert the first already programmed key into the ignition and turn to position II
• Turn back to 0 and remove the key
• Insert the second already programmed key into the ignition and turn to position II
• Turn back to 0 and remove the key
• Key programming mode is now activated and you have ten seconds to:
• Insert the unprogrammed new key into the ignition and turn to position II
• Turn back to 0 and remove the key
• Allow 10 seconds to pass for the system to exit programming mode.

Not that it is any good to you with only 1 working key

Radio Frequency Programming Instructions:

• Insert the ignition key and turn from position II (Ignition) to position 0 (All off) and back four times within three seconds.
• Remove the ignition key. The locking control system is now in "learn mode" for the next 20 seconds and the red warning system LED (By the clock) stays on continuously to indicate this.
• During the 20 seconds press one of the transmitter buttons. The remotes signal and code number is learned by the locking module and is indicated by flashing the warning system LED.
• Wait until learn mode times out (20 seconds) or switch the ignition back to ON
