Answer
OK, You have a problem with the anti-theft and PASS-KEY systems due to a fault in the:

ignition key.

Ignition key lock cylinder on the steering column.

A short or open circuit in the ant-theft system.

A faulty PASS-KEY Module.

The starter relay.

In MOST cases the fault is the PASS-KEY module, But NOT always. If you have some electrical and mechanical automotive skills or have a facility other than a Cadillac dealer who does your repair work, You need to e-mail: [email protected] for numerous pictures and directives to fix this problem.
