I need to reset the anti theft system

A nice simple answer, you can't. Think of it this way, the car doesn't know you are the owner, and it is there to stop exactly what you are trying to do. You have two computer ECM and BCM, plus the antitheft module and a number of sensors all trying to stop you. All you have to do is the re-learn procedure. Plan B is an auto electrician or alarm / radio installer or auto locksmith.

30 Minute Re-Learn Procedure

1. Turn ON the ignition, with the engine OFF.
2. Attempt to start the engine, then release the key to ON (vehicle will not start).
3. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF.
4. Turn OFF the ignition, and wait 5 seconds .

Hello Vickie,

It sounds like your battery is dead, or if you're really lucky, your battery cables are corroded.
Pop your hood and inspect your cables at the battery, especially the Positive (Red) lead. If you see white oxidation build up, then the cables need to be removed and cleaned.
If clean, then the battery may be dead. It can be beyond its service life (sometimes there is a date code on the battery so you can determine age).
If the vehicle can be jump started; after starting, turn on heater fan and headlamps to high. If the lights are dim, then the alternator may be bad or is going bad.
Start with the battery first, then go from there.

the anti-theft system may have activated and you will have to reset it.

The problem may not be with anti-theft but with a bad fuel pump,cam/crank sensor etc. Also, you may try unlocking the drivers door with the key. On most cars that is the standard method for disabling the security system.

I have already gone into this.

If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key's key-less entry signal, or there may be a fault in the anti-theft module or wiring.
There is a reset procedure to stop this anti-theft light flashing.many a times this helps The reset procedure is as follows:-- Reset the alarm by locking and unlocking the drivers side door.Do this a couple of times and then check it will reset the factory security system . If the reset procedure does not helps then its time to get the anti-theft system checked.There is a short circuit in the anti-theft system wiring.

how to reset the anti theft system for my 2006 dodge ram 1500

You may have a faulty ingition. Otherwise you have the very common GM anti-theft system. If you have a flashing anti-theft light with key in igniton, then this is what you should do:

Put key in ignition, turn to ON position (Do NOT Start)
Leave in on position for EXACTLY 10 Minutes
Then while watching the anti-theft light, as SOON as the light turns off after 10 minutes, START CAR IMMEDIATELY after light turns off.

This will reset the anti-theft
