Did you switch the new battery over directly after you removed the old one? If so try disconnecting the car battery for a few hours, then when you put it back on put the live "red" on first then the "negative" black second. this often resets the immobiliser.
Hope that helps.
p.s in some cases with other makes you have to leave the battery off over night as the immobiliser if factory fitted has a battery backup built in. this needs to run dead.
p.s.s also try lock and unlock with the key not the remote.
If by turning over you mean that the engine isn't turning when you turn the key, then you have a failure in the starting system. (check battery, connections, relay and starter) If the engine turns but dosen't start, try locking and unlocking the drivers door to re-set the security system.
sometimes it depends on the type of allarm, if it is factory fitted they are a nightmare to do as most of the wireing for the allarm is intergrated into the loom, where as if it is an after marked alarm ( one fitted later on ) it shouldnt be to bad but still a long and complicated job to find all the wires and reconnect the originals bypassing the immobiliser/alarm if you are a complete novice this should not be attempted as you could immobilise the car completely, best thing for you to do is get an auto electrician to have a look at it for you, sorry its not much help
should have an immobiliser in it,you can tell if theres a flashing light on the dash somewhere that illuminates when the car is off,it will be a factory thing not fitted later ,if you cant see one anywhere it may not have one,it would be listed in the owners manual if you have it
there is often a small back up battery in the immobiliser unit itself, if you can locate this unit and replace the battery with the ignition on / engine running, then it should not need recoding and work fine after that. The other thing that could be wrong is the key battery (if the fob has one) or the transponder chip in the key head. If the key signal is low the immobiliser lamp will light during driving, but this does not explain the alarm going off. That is more likely either a poor vehicle battery, alarm / immobiliser back up battery, or another electrical fault such as water leakage into a tail-light or even the alarm unit itself when it rains. A lot of alarms are voltage sensing and when the vehicle is parked they will alarm if the battery voltage changes for any reason, though not during driving so the battery in the immob is my first choice to look at.
The ST18x didn't come with a factory fitted alarm, so this is going to be more general.
Your alarm will have a manual disarm somewhere. If you have a small cylindrical device with your keyfob, there will be a receptacle somewhere near the drivers seat. You need to open the door and press the two items together. If not, you may have a button hidden somewhere around the place. In this case the procedure is usually to hold the button while you insert the ignition key and turn it to the ON position.
Some alarms have a small round key. If your alarm has one, or if your keys came with one and you didn't know what it was for, you can open the bonnet, pop a little cover on the alarm box (it will be bolted to the firewall, usually on the right hand side as you look at it) and turn it off until you can get it repaired, or get a new one fitted.
If none of this works and your alarm is an alarm only and not an immobiliser, you can simply open the bonnet and cut all the wires going into the alarm. If it is also an immobiliser, don't touch anything unless you're handy with a soldering iron and multimeter and have a few hours spare. (You would need to pull the cover down from under the steering wheel, then start taking electrical tape off the big block connector with thick wires, and then start rebuilding the wiring that's been chopped to make way for the immobiliser system on a colour-matching basis.)
I would take off the alarm and see if the problem goes away. If it does you know the problem is with the alarm. I am in the alarm business and will not have one on any of my vehicles unless they come that way from the factory.
unlock your car with the key, put the key in the ignition switch, remove one of the battery terminals now switch the ignition to the running position then put the battery terminal back on this will bypass the rovers immobiliser and alarm system
