What is your question?

My 1991 Q45 Alarm goes off when I open the Driver Side Door. Shuts off when I turn the key in the Passenger Door. I replaced the whole assembly on the driver side for the Door sensor and the rubber boot only on the Passenger side. The Rubber Boot on the Hood is torn off and Infiniti tells me they donot even sell the part and neither does O'Reilley. My issue may be to reset the whole system after replacing the parts. Any suggestions. Is simply locking and unlocking both the doors a couple of times take care of this?

How long has your 1991 INFINITI Q45 had this problem?
