Are the factory keys required to arm the alarm?

I have ordered a set of keys through the dealer, in the mean time I have been trying to see if the alarm works. So far I have not been able to arm the alarm. The only key I have is an aftermarket, laser cut key.

If this key should arm the system, then I can start trouble shooting, if not I'll wait for the real keys to arrive.
