It starts with the security light and then gets worse till the car won't start anymore. The security system (VATS/Passkey) installed on these GM cars is anti-owner more than an anti-theft. There are 3 parts involved:

  1. The chip-key
  2. The lock cylinder
  3. The TDM (aka the brain of the system)
if any of these parts fails or is even slightly malfunctioning, the car stays stuck where you are and you only get a dealer asking you about 1,000$ to fix it. And all the 3 parts have a quite short lifespan. Way too many people got in this situation (including myself). I don't recommend any partial solution or any used parts as it would happen again way too soon to be acceptable and if it happens 100 miles from home (like it happened to me....) it's a big burden. I finally made it to save my beloved 94 Park Avenue (with the exact same system that is installed in your car) with a solution that I found on the internet and that bypasses the entire factory security system, all 3 pieces altogether and you can even remove the TDM at the end and use 99c keys without chip. The product I used is at http://newrockies.com and is still working perfectly after 5 years. Don't go to the dealer!

2009 chevy traverse wont start after hooking amp up car was fine


OK. you had the battery disconnected. Here is what you do. Turn on the key. The security light will begin to flash. Wait (about 10 minutes) with the key in the ON position. The security light will stop flashing. TURN OFF the key. Then, turn on the key and start the car. Security system is supposed to prevent theft for a 10 minute delay. This usually discourages any thief. This will work, You just need to be patient with the 10 minutes. It seems like an hour when you wait ten minutes for that security light to stop flashing.

How do I reset the anti theft system on my Suzuki XL7? A new battery was installed and messed my system up


which one.
radio antitheft
car doors. (alarms) Content Theft Deterrent (CTD)
or immobilizer.
say what messed up means.?
the CDC system must be armed with the fob.
is that failing? I can not arm the system or it will not disarm. on my command?

my guess is arming. fails

  1. Turn OFF the ignition.
  2. Exit the vehicle.
  3. Important: The system is not armed if the doors are locked manually. The keyless entry transmitter or the door lock switch must be used to arm the CTD system.
  4. With a vehicle door open, lock the doors by pressing the LOCK button on the keyless entry transmitter or by pressing the LOCK button on the door lock switch. The system will begin the arm sequence when all doors are closed. The CTD system transition to the arm delay state when the final door is closed. The security indicator will illuminate steady when in the arm delay state.
    If the keyless entry transmitter LOCK button is pressed after the vehicle doors have been closed, the system will transition directly to the arm delay state with the indicator on steady.
  5. The system will arm approximately 30 seconds from the time that the system has entered the arm delay state. When the security indicator transitions to flashing slowly, the system is armed.
    Alternately, if the LOCK button on the keyless entry transmitter is pressed a second time, the system will arm immediately, bypassing the 30 second delay.
if this fails try the Second fob.
if the 2nd fob fails, then pull the battery neg lug, for 5 minutes
and put it back.

the full system rules are in the book called, FSM
seen here, read it for who to diagnosis this problem if it continues
just 4 bucks to read all facts
https://suzukipitstopplus.com/Products/10182-2007-xl7-service-manual.aspx

the book also tells you all things messed up with battery pulls.

good luck.

Anyone got the code for a sony radio code M048603


A keycode anti-theif system is featured in the audio unit, if the unit and/or the battery is disconnected, the audio unit will not function again on reconnection until the correct security code is entered. You will need to provide proof of ownership and a legitimate reason for wanting this information, the vehicle's selling dealer may be able to help. Note that these units will allow only ten attempts at entering the code - any further attempts will render the unit permanently inoperative until it has been reprogrammed by the dealer themselves. At first, three consecutive attempts are allowed; if all three are incorrect , a 30 minute delay is required before another attempt can be made. Each of any subsequent attempts (up to the maximum of ten) can be made only after a similar delay.

The red security light comes on in my buick century 2000 and sometimes it starts and sometimes it doesn't! it may take 5 minutes to start or sometimes an hour!1! please can i disconnect a fuse or


If it is an aftermarket system you should be able to disconnect it.
You may have to look for extra wires attached to the fuse box to find the source of power.
Factory systems usually have the word security in the cluster.

Delay in Start on 2000 Grand Cherokee Ltd 4.7 engine


To check the solenoid internal contact, you'd need to remove the starter and remove the solenoid cover. Inside you will find a brass wheel that contacts the positive battery lug. You can remove the wheel and reverse it and turn the lug 180 degrees, providing new contact surfaces. Seems that you've done just about everything else. You can also use a test light attaching it at different points to find where the actual delay is occurring. Normally security will allow cranking but will not allow starting.

Chevy Impala delayed starting after removing radio


no this is not a radio problem. disconnect your aftermarket acessories and plug your radio as it was from factory and see if u still have this problem. there is probably a problem with communication because of your fm modulator or your ipod. radio does not cause a security problem on this year vehicle
