i hope your getting all these keys back? those type of immobilizers have a small box that wires into the remote start and you install an extra key inside of it...usually for my customers peace of mind i install the head only and give them back the key part....anyway this thing wires to power and a few other things iginition etc..but one of the wires is a wire that grounds the immobilizer during remote start...this energizes a coil inside that surrounds the head of the key and transmits that frequency through an antenna that ends in a loop that is supposed to be mounted around the key cylinder in the steering column or wherever you stick the ignition key in (dash or console, wherever the ignition key goes) this tricks the factory system into thinking that you have a key in the cylinder....sounds to me like they are haveing trouble getting this antenna to stay put...they can be finicky and some of them even specify which way to run the wire that goes back to the immobilizer box.....
i still dont have a good answer for the lock/unlock unless maybe your car locks and unlocks when you put the key in the igintion? then it could be that they have taken a shortcut and wired this thing to constantly be on, this would also account for tthe remote start not working because most pats systems will not allow you to unsuccessfully try to start the car more than 2 or 3 times before not letting it start for a few minutes...
ok im having a vision......the imobilizer gets constant power and recieves its negative input from the brain during remote start....if they have tried to shortcut this by merely grounding this wire then the immobilizer will have constant power..it also outputs to the ignition wires but not the starter wires so it could make the system think you are putting the key in and turning it without actually making the car crank because the system brain is not recieving the remote signal if your car locks the doors when you put the key in and turn it and then unlocks when you take the key out i would suspect this MAY be whats happening.....which would also explain why it wont remote start because it is cycling the ignition without cranking it and then you go in the car with a different key and it starts......if it doesnt always start with the key then they need to use the keysence and a relay to make it work because some systems dont like to see 2 keys at once.....

i hope that made sense
