C180 R reg Key Sync procedure

Dear all, thanks in advance for your help.

Electronic key was being a bit "sticky" in the ignition in the last few days, then last night I couldn't lock the car. Thought it was probably the batteries in the remote and so changed them but it took me longer than 30 secs (I didn't realise this was a problem until reading about it on other posts here!).

I now cannot operate the locks or start the car. From doing my research it looks like this may be a sync problem with the key. The manual doesn't tell you how to resync the key.

I have checked the infra red is working (by looking for the bulb lighting with a digital camera - it does) and the red LED is lighting when the buttons are pressed.

The key type is 3 buttons with a slide out mechanical element.

Anyone know the resync procedure for this car?

Many thanks
