I have a 2001 jeep grand Cherokee Laredo and I was wondering if anyone might be able to help me, when I first bought my jeep I could lock and unlock the doors with the wireless remote and the lights would flash, when arming it the horn would sound all normal right. But I recently needed the engine replaced and when I got it back the lights now won't flash when locking or unlocking and the horn doesn't sound when locking or arming the jeep any ideas? Also when the jeep gets shut off after I drive it it doesn't unlock all the doors is this normal?
