Hi,

You don't use key 1 and 2.

Just Key 1 and then a ground wire connected to the two colours that Simon mentioned.

There is usually a black loose wire on the head unit loom marked GND. Try using that instead of just grounding to earth and then try programming the head unit again.

As Pete said, you can indeed use a multimeter on the cars steering wheel wires to check they are functioning but it is likely they are ok.
