2006 PT Cruiser has multi tone chime when Ignition is turned off. What does this indicate?

Takes the master key to get it started again. The security gives you 3 tries to get the vehicle started, after the third time, it kills the starter.

NOTE: The generic electronic module/central timer module (GEM/CTM) is connected to the ISO link and is diagnosed through the data link connector (DLC) with a scan tool.
There are five warning chimes and lamps the GEM/CTM controls: headlamps operating without the ignition on (chime only), door ajar (chime and lamp), key-in-ignition (chime only), driver seat belt warning (chime and lamp), and message center.


Audible Warnings Warning Condition Lamp Duration Audible Duration Audible Output Safety Belt 60 Seconds 6 Seconds Chime, 60/Min. 740 Hz Key In Ignition - Continuous Chime, 120/Min. 740 Hz Headlamps On - Continuous Chime, 240/Min. 740 Hz Door Ajar Continuous 1 Second Single Tone, 1000 Hz Message Center (Tone Request) - 1 Second Single Tone, 1000 Hz
When the is turned to RUN or START from OFF or ACC, the chime will sound for six seconds or until the safety belt is buckled.
The will turn on for 60 seconds or until the driver safety belt is fastened. Both the chime and the lamp turn on at the same time.
If the safety belt is buckled before the ignition switch is turned to RUN or START, from OFF or ACC, neither the chime nor lamp will be activated.
Anytime the is changed to RUN from START while the safety belt warning indicator is activated, the safety belt warning indicator will remain activated until either the timing sequence has been executed or the safety belt is buckled.
When at least one door is ajar and the key is in the RUN position, the door ajar cluster lamp is activated and remains on until all doors are closed. A warning tone will sound once any time the key is in the ignition switch and any door is open.
The key-in-ignition warning will sound when the driver side is opened with the key in the and the in OFF or ACC. It will continue to sound until the key is removed, the is closed, or the is in RUN or START.
The headlamp-on reminder chime will be activated if the headlamps or parking lamps are on, the key is not in the ignition switch, and the driver door is opened.
A single tone will be provided each time a ground signal is received from the message center. A one-second tone will sound for warning indications from the message center. A 100 milli-second tone will sound for each message center button depressed.

is it a scraping noise or a clicking noise. a scraping noise could indicate a brake noise when turning have the brakes checked in the front. if its a clicking noise only when turning to the right then you may have a bad cv joint on the right half shaft. replace the half shaft assembly.

I believe you are referring to the immobilizer in your key for your car. Unfortunately there is not a way around this factory anti theft system. However most delearships have the ability program new keys for you.

If you had two valid keys that were already programed to the car's immobilizer you can simply buy another key with a programmable immobilizer chip, usually referred to as a sentry key. These keys are available at some hardware stores for cheaper then you would find at a dealership. So if you have the old keys and a new blank key you can follow the following procedure in most cars to program the new key:

1. Bring the replacement sentry key to a hardware store or dealership. Have it cut to match the original valid sentry keys.

2. Place the first valid key into the PT Cruiser's ignition and turn to the ON position for a minimum of three seconds and a maximum of 15 seconds. Turn ignition switch off until it is in the LOCK position and remove the key.

3. Within 15 seconds, insert the second valid key and turn the ignition to the ON position. Wait ten seconds or until a chime sounds and the vehicle security light begins to flash. Turn the ignition off until it is in the LOCK position and remove the key.

4. Within 60 seconds, insert the new blank sentry key into the ignition switch and turn it to the ON position. Wait 10 seconds or until you hear a single chime and the vehicle security light stops flashing. Look for the indicator light on the dashboard. If it turns on for three seconds and then turns off, the key has been successfully programmed.

I just had the same problem happening with my 2006 PT Touring. Took it to the dealership. The issue was the electric parts of the ignition switch. They replaced it and all is well in the world again.

ATTENTION: You MUST HAVE one working remote to add one more to the system. If you do not have one working remote right now then these instructions will not work. You will have to have a Locksmith or dealership use a computer to program the first remote for you.

1. Turn ignition to run position (as far as you can go without starting engine).
2. Using any Working remote, press the UNLOCK button for 4 to 10 seconds.
3. Within the specified 4 to 10 seconds, continue pressing the UNLOCK buton and press
the PANIC button for 1 second and release both buttons at the same time. A chime will
sound within 3 seconds to indicate that the vehicle has entered remote programming
mode.
4. Within 30 seconds of the chime, press any button on all remotes to be programmed
including previously programmed remotes. A chime will sound after each remote is
programmed.
5. Turn ignition to OFF and remove key.
6. Test all remotes.

There is no separate fuse for the fuel pump on the '06 and later PT Cruisers. If you're attempting to do something that require the engine to turn over, e.g. a compression test, use a manual remote starter connected between the starter solenoid and the positive battery terminal. The fuel pump won't be active with the ignition turned off.

If you don't have the Panic button then sorry, you can't program yourself, the dealer will have to program it to the RKE (Remote Keyless Entry) module in the vehicle, using their DRB scan tool.
