how can I fix my peugeot 806 keypad ?

I have a Peugeot 806 eden Park model and the pre ignition keypad buttons have finally worn out, making it very difficult to start. Is there any way to bypass the keypad and just stick the key in and start it. It's a reliable vehicle but quite old so don't want to spend a fortune on repairing it. any help gratefully appreciated, thanks.
