I have a 2001 Bmw 740i and I just replaced the battery and now the car will turn over but won't start and the alarm randomly goes off

It thinks you are stealing it!

You have fallen foul of the anti-theft system!

Number one tip, maintain power when changing batteries with a couple of lengths of wire or jump leads.

Disconnect the battery for 2 hours. Put your key in the ignition, but not on. Reconnect the battery. The ECU will pair the chip in the key and the chip in the ignition lock. The ECU will then release power to the ignition system.

At present the ECU thinks you are trying to steal the car with a key that just happens to fit the lock. Clever stuff eh? Let me know how you get on by clicking COMMENT under my post.

It must be 2 hours to dissipate all power in the car held by electronics.

How do i. Install an alarm on my bmw 1995 325i

The stock alarm systems on the e36's were wired all the way into the transponder key system. Best solution is probablly to go aftermarket. I have a 95 with an alarm and it isn't the greatest most bmw alarms up til 2000 or later you could break a window and it wouldn't go off. It was just in case someone tried to open the door. Go aftermarket and they are usually much easier to setup. Most wire right to the battery for power or you can steal power from something else. Good luck

I have a 1996 chevy cavalier z24 manual transmission. My car cranks but wont turn on. I changed the ignition Switch with a new key. The Anti theft alarm stays on. i cut the alarm off because the horn is...

Check timing belt. Remove the oil filler cap and look at the rocker arm. If you get someone to turn the engine while you watch and you see no movement... it's a broken belt. If you see movement, perhaps the belt has slipped. Replace belt and re time.

check starter for power on main battery wire and on smaller wire from ignition switch while someone turns the key if your getting power on both wires it's the starter if you want you can also tap on the starter and starter solenoid while the key is being turned and see if it starts but it does sound like starter to me if your not getting power to the starter on the small wire make sure your alarm isn't interfering and check ignition switch

Alarm problem

The alarm system 'thinks' someone was trying to steal the car. You will have to reset it.
Try this;
remove key from ignition.
lock and open the car door with the key as normal.
or disconnect/wait a while/reconnect the battery
or you may have to contact the alarm manufacturer.
