How can I start my suzuki baleno again having lost the original key?

My wife left our suzuki baleno at an airport carpark while travelling away on business. On return, she could not trace the car key. It was lost. We had another key cut after the car was towed away but it can't start the engine as the original had an in-built immobiliser. I am failing to get a duplicate quickly but also need to use the car. what should I do?
