Ok here's the deal.....the hood sensor is on passenger side next to power distribution center (fuse box) ..... Did you program the new key/transmitter? With everything shut get in car and turn key from off to run....not start....run, 5 times. The car will lock itself on the 5th cycle, then within 3 seconds hit the unlock button and the doors will unlock, then turn key back to off position. You may also have a problem with your PATS system like I do. If you hit the lock and get two honks press the unlock button again once and then the lock again. Did you get one honk? Let me know
