Hi,

Hope someone can give me some needed help, please :(

Symtoms:
  • Keyless Entry/Start (KG) NOT Working - 'Key Not Recognised' appears on dashboard
  • Remote Locking (RF) NOT Working - Cannot Lock/Unlock car at any distance
  • Infrared Locking (IR) is Working, I am able to Lock/Unlock the car if I point the key(s) directly at the IR sensor(s) on the door handles (Where Boot, Doors and Petrol Cap all lock/unlock), which means the PSE pump is working.

So far I have:
  1. Replaced main battery in boot
  2. Charged Battery under bonnet (Was more or less already fully charged)
  3. Replaced batteries in both key fobs
  4. Checked all fuses (With 12v light tester)
  5. Tried a couple of steps to sync the keys (Not sure if any of them were correct)
  6. Connected to STAR, where there was no errors shown, however the '750 CGW. N93 (Central Gateway, Control unit)' was shown as 'NOT PRESENT' ??? (Not sure if this is normal or not)
  7. Disconnected both batteries (overnight) in the hope a shutdown of the system resolved it
  8. Unplugged all SAN connectors (Located behind drivers seat) one by one
  9. Tested all other electrics in the car and everything else works including the alarm.
The car had been stored in the garage most of the winter, so cant be caused by a water leek (Boot and inside car is bone dry).

My first thought is what links the KG and RF systems, are the reliant on each other if so what components do they share?

Thanks in advance :)

Kg uses the same rf as the normal locking so if rf doesn't work then Kg won't either.

Get it on star, and check to see if the key rf is being received, if not then suspect key or antenna amplifier.

Thanks for confirming RF and KG are linked.

I did get it on a STAR but I dont think that was checked, might be wrong. There wasnt any errors shown I know that much.

Sounds like I might need to get it plugged in again, I didnt realise that could be checked.

You can check whether key signal is being received and whether its the right signal for the car so can test whether the key is outputting rf or if the antenna isn't receiving it.
