Put another motor in,when i connect the battery the hazards flash and will not go off, will not let it turn over,doesnt have keyless entry and is auto v6

It sounds like you may have a problem with the keyless entry fob. Try replacing the battery. Repost with your results.

the hazard switch is the problem or it is cause by passive alarm, remove the hazard switch or hazard fuse and observe the function of the lights, if lights stop flashing, change the switch, if continous flashing check the keyless entry reciever or the body control module

disconnect battery for 10 minutes.

Replace the battery in the remote. I have a feeling that it needs to be replaced, after replacing the battery, hold the lock and unlock buttons down for about 7-30 seconds for the remote to understand that it needs to pair with the car. The locks should lock, unlock then lock again.

Yes that is what you do to program the remote if you had one.

Faulthy sensor or a relay, try to reset, by dis/re-connecting the ground cable from the battery, remove the ground cable ( - not the +) wait 1 minute reconnect the ground cable.

It wouldn't be the car battery, but since you just purchased the car, the dealership should correct the problem. Bring it to their attention right away. Did you get any kind of warranty? Most dealers have at least a 30 day warranty for things like this.

if its early 05 round heart shaped remote it needs programming into system at dealer with Tech2
later 05 to 07 had square (rectangle) shaped remote

You need to program the remote. Get in to the car and LOCK all doors with the switch on drivers side door. Take the key and insert it into the ignition cylinder in and out 6-10 times, until the flashers/hazards flash on your dash board. Or just keep putting the key in and out (nice and easy now, not fast) until you see the lights on dash flash. After the lights flash, turn the key into ACC mode to make the whole dash light up.(do not start car) .With the key in ACC position, hit any button on remote, that will make the hazards flash again. Turn key off and unlock door with switch again. Open door.DONE.
Good luck.
