how to disconnect alarm

the car should still be under warranty, i would make a trip to the dealer

Agreed, don't just start cutting wires or you could have bigger problems.

ok. i had the same problem. first on the driver side remove the panal where the drivers knees would be. when u do u will be able to see ur fuses and a bunch of wires. way up in the dash there will be 2 modules, one has a a 6 wire connector and one has a 10 wire connector, unplug them both, then ur alarm will be off but it kills ur starter, to keep the starter workin connect the 5 and 6 wire from the 6 wire connector together, it should work if not let me know.

Don't hack your car. Bring it to the dealer, it will most likely be covered under warranty.
