How to disable anti theft system on 2003 Nissan Altima

If you disable the anti-theft system that easily, it wouldn't be much of an anti-theft system, would it.?

ignitiom coils? main fuse blown?(under bonnett)

There is NO way to disable anti-theft. It wouldn't be called anti-theft if you could disable it.

Anti theft system not possible to over ride

Anti theft system is built into your car's Engine Control Module. It cannot be disabled according to everything I've read in the Nissan forums.

Pull the fuse

u need a machine to recode the system

On most cars the security system can be disabled by locking and unlocking the driver's door with the key.

Unfortunately, the keys have an anti-theft chip in their bodies that communicates with the car's system.
Try Googling ("Nissan/car key programming" for a cheaper price or phone independent garages. The keys can probably only be done by an authorized Nissan dealer. Also, phone locksmiths for their opinion.

Hello.
It is very likely that the terminal is fine. Many vehicle owners are not aware that the newer factory installed anti-theft systems will lock down the car, ( prevent it from starting ), if the battery is disconnected for more than just a couple of minutes. In the future if you need to disconnect the battery, make sure that you dis-arm the anti-theft system first

You should be able to find out how to dis-arm/over-ride the anti-theft system in your owners manual.

I hope this helps you.
