You could try the trick that sometimes works on the 451 -
Put the key in the ignition, turn it to position 1, and while still plugged into the ignition, press the unlock button for a few seconds. If it works, you should hear the security system beep.
I’ve also heard that putting the driver’s side door and exercising the lock a few times has been known to resurrect a wonky key.
