I was swaping out the opti and I reconnected the battery and now it wont start, but there is a quick clicking flutter coming from the glove box area and the anti theft light blinks very fast when i have the key in the run possision and the keyless remote doesnt work and the doors will lock but not unlock with the switch, is it just low battery voltage or a anti theft thing?

to me the tapping sound makes it almost like your battery is dying....I could be off on that one but try putting a charger on there or jumping it off and see what happenes. Also make sure you wired the opti correctly.

Maybe you did not get your battery connected tightly.

agreed, make sure those battery connections are clean and tight.
