Well I was acquainted with car alarms 10 years or so ago. So if they are using the same technology, one type is the key has a pill in it which looks like a black dot on the key. It really is a resistor, so you can measure the value and bypass the pill. The other was a transmitting type in a the large head of the key, in which you could use what we called a bypass kit, so you can install your own alarm system. Otherwise, there are nice instructional videos on youtube for your type of car and alarm. Good luck and hope this helps.
