You didn't say whether this was a factory or an aftermarket security system. Factory systems can usually be reset by using the key in the driver's side door, and turning key to "lock" then "unlock". An aftermarket system may benefit from having the ignition key in the "ON" or "RUN" position.

Is your anti-theft security system original equipment or aftermarket? If aftermarket, take it back to the installer for service. If it is an OEM (factory-installed) security system, check your owner's manuals for instructions on how to reset the system.

My 01 Acura MDX Touring Edition alarm keeps sounding while trying to connect the jumper cables in order to jump start it after the battery has died a couple of times. Why is this happening and how do i...

Forget about the alarm . The problem is your trying to jump start a dead battery. Replace the battery and reset the cpu with a code reader and the problem should be solved.

I have an Acura MDX 2003 and can't disable the factory security alarm... I don't have a remote

If it's a cheap aftermarket alarm, check for a red wire coming off the hot side of your battery with an inline fuse. If it's not, try to locate the alarm "computer" under the driver's side dash or nearby your fuse panel. You'll find a black box with a wiring diagram glued to the side, normally strapped to a wiring harness or other fixed element. If this is the type of alarm you have, you'll need to trace each wire coming from the alarm computer and unclip each fastener that's clipped to your vehicle's factory wiring. The trouble with these types of alarms is that they can get power from a number of sources (stereo, interior lights, etc.). Good luck with this one!

The brake alarm just came on unexpexted on my acura MDX

Check brake fluid level and have a look at the brake pads, make sure they aren't worn down and check security/condition of the wires from the pads. I assume you don't mean handbrake on indicator.

Radio Security Code

I think that your only bet would be to take it to an Acura dealership. The service department should be able to reset the radio.
