Anti theft mode enable this message comes in my system pls give me solution it comes after one hour

How do I get my Mercedes out of anti-theft mode?

Look for a button that allows you to slide the physical key out of the fob. Step 2: Turn the vehicle key to unlock the car door without releasing it. Hold the key for 30 seconds in this position. This will signal to your car's system that you have the right key, and will enable you to bypass your car's alarm system.

Ok disconnect the battery cables like you were instructed in the first answer the when you reconnect them the vehicles alarm will go off when it does use your keyfob to shut of the alarm and it will come out of theft mode and start if you don't do this you will have the same problem no start then when you first put the key in turn it to on but don't crank the motor this gives the self test for the computer to start and you'll see dash lights for check engine and other sensors go out and you will here the fuel pump energize now crank and start give it 10 minutes running to relearn the sensor values then drive the car ok please make sure that there is nothing hanging on the shift lever and you only have 1 chip key in the car with you otherwise it will pick up both chips and will not start good luck stephen

You will need to call a locksmith on this.

This is a very common problem on GM vehicles. GM's anti theft system relies on many things to be working "just right". If they are not, your vehicles goes into anti theft mode and locks out the starter and/or injectors. Leaving your car "immobilized". The hard part is finding which part of the system in failing. The KEY, the IGNITION/LOCK CYLINDER, or the actual TDM computer (Theft Deterrent Module). Any 1 one of these parts will be 100-700 bucks plus dealer fees and labor. I have had great luck in just bypassing the whole system. If you do this permanently, you'll never have to worry about this again, and you can do it yourself in about an hour.

This is Acer AL1916W is 2008 model year, you just bought it brand new? it should come with the CD for edisplay management software that you need to install in your PC to enable/disable the anti-theft. I would take it back to where you bought it from and have them remove the anti-theft since the seller has activated it.
Please read the user manual that come with this monitor for details.

try to go to bios by pressing f2 on start ..and after that choose optimal factory defaults from the list ...it will be somewhere there a line named exactly like that ..after chooseing it ..press f10 to save changes..and reboot ...if it set from there it will go away..

If the anti-theft light is flashing then it is in theft mode. If this is the case turn the key on and wait 1 hour then cycle the key to see if it starts if it does you have a anti-theft problem see dealer. sorry.
