Question about 2006 Chevrolet HHR

2 Answers

Chevrolet HHR horn and lights flash every few minuets.

I left my keys in my pants with the keyless entry. I am wondering if they got wet and is shorting out and causing the horn to engage.

I had to use my spare key to turn the engine on to stop the horn perhaps that caused a problem.

I tried to find the fuse box and pulled two pannels that may have been computer hardware and now my engine light stays on, my speedometer doesn't work and my transmission stays in the same gear.

My gas cap is tight and I have less than 45,000 miles.

Can you help?

Theft Deterrent Arm/Disarm Modes
Important: Although mode 2 provides increased security, the content theft deterrent system disarms only by pressing unlock on the keyless entry transmitter. This can pose a problem if the keyless entry transmitter is damaged, lost, or inoperative for any reason while you attempt to disarm the content theft deterrent system.
Mode 1: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter. The system does not arm when you lock the doors with a power door lock switch.

Mode 2: The system arms when you lock the doors with the keyless entry transmitter. The system disarms when you unlock the doors with the keyless entry transmitter. The system does not disarm when you unlock the doors with the key.

Mode 3: The system arms when you lock the doors using a power door lock switch or the keyless entry transmitter. The system disarms when you unlock the left front, right front, or liftgate door with the key or the keyless entry transmitter.
Changing the Feature Customization Modes
  1. Turn off the IP dimmer switch.
  2. Turn the ignition switch to the LOCK position.
  3. Remove the BCM PRGRM fuse.
  4. Turn the ignition switch to the ACC position. The BCM flashes the fasten belts indicator and sounds the chime 4 times, which indicates that BCM type 4 is installed on the vehicle. At this point, the BCM has entered the feature customization mode.
  5. In order to change the theft deterrent/shock sensor mode, turn the headlamp switch from OFF to PARK and back to OFF.
  6. The BCM flashes the fasten belts indicator and sounds the chime a number of times equivalent to the theft deterrent/shock sensor mode. A transition past mode 4 repeats the sequence starting with mode 1.
  7. Complete the following steps in order to change the theft deterrent arm/disarm mode:
6.1.
Insert the key in the left front, right front, or liftgate door lock cylinder.


6.2.
Rotate the key from the center to the unlock position.


6.3.
Press the horn button on the remote keyless entry transmitter.


6.4.
Count the number of chimes that you hear. The number of chimes tells you which mode you have set.


6.5.
Press the horn button again in order to change the mode. Continue to press the button until you hear the number of chimes that indicates the mode that you want.


6.6.
Turn the key back to the center position and remove the key from the door key cylinder.

In order to exit and save the current feature customization modes use the following procedure:

  1. Turn the ignition switch to the LOCK position.
  2. Reinstall the BCM PRGRM fuse.
If you are unable to change locking modes Theft Deterrent System Feature Customization Inoperative

I have a 2000 pontiac trans am. when i set my alarm my haedlight pop up. they never use to. replaced module,and headlight motors,still didn't fix it.


In your owners manual on pages 2-19 and 2-21 tells you how to change this.

Entering Programming Mode
1. Turn the ignition key to RUN, then to OFF. This will
disarm the content theft-deterrent/alarm system
(if equipped).
2. Remove the RADIO fuse. This fuse is located in the
main fuse block which is located on the left side of
your instrument panel. The radio fuse is on the lower
right-hand corner of your instrument panel. See
"Fuses and Circuit Breakers" in the Index.
3. Turn the ignition key from OFF to RUN three times
quickly (within five seconds). The vehicle will
respond by locking the doors, unlocking the driver's
door and releasing the hatch. Your transmitter is now
ready to match the vehicle. Leave the ignition
in RUN.
4. Press and hold the LOCK and UNLOCK buttons on
the first transmitter for 15 seconds. The vehicle will
respond as in Step 3.
5. Repeat Step 4 for the remaining transmitters.
6. When you have finished matching all of your
transmitters, replace the RADIO fuse.
7. Check that all transmitters work by pressing
the buttons.

Programmable Modes
Your vehicle can be programmed to one of the
following modes:
Mode 1: All Off (The headlamps will not flash and the
horn will not sound to provide you feedback that a
lock/unlock command has been received by the remote
keyless entry transmitter.)
Mode 2: Horn and Lamps/Lamps (Your horn will sound
briefly and your parking lamps will flash when you
press LOCK on the remote keyless entry transmitter.
Only your parking lamps will flash when you press
UNLOCK.)
Mode 3: Horn and Lamps (Your horn will sound briefly
and your parking lamps will flash every time you push
LOCK or UNLOCK.)
Mode 4: Lamps (Your parking lamps will flash every
time you press LOCK or UNLOCK.)
Mode 5: Lamps/Horn and Lamps/Lamps (Your lamps
will flash upon the first press on LOCK, your lamps will
flash and your horn will sound upon the second press
on LOCK and your lamps will flash upon any press
on UNLOCK.)
Vehicles are delivered programmed in Mode 5.
To change the mode, do the following:
1. Press the UNLOCK button on the remote keyless
entry transmitter.
2. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is
set for.
3. Press the UNLOCK button, again, on the remote
keyless entry transmitter until you hear the number
of chimes that correspond to the mode selection
you want.
The mode you selected is now set. You can either exit
the programming mode by following the instructions
later in this section or program the next feature available
on your vehicle.

When programming is complete, turn the ignition to
OFF and reinstall the RADIO fuse.

Diagnose keyless entry system of 1997 Cherokee


Before replacing any Relay. Try disconnecting the negative side of the battery for at least 2-minutes to de-energize the security system, re-setting itself. The reconnect the battery and try your security (and options) system again.
The only other big question that you will have to know: is this a factory installed security system or an aftermarket security system? This makes a difference in security systems, relays etc.

    HORN WILL NOT SOUND BUT DOORS WILL LOCK WHEN I USE MY KEYLESS ENT


    The title of you problem mentions the horn but the actual problem mentions the flashers? Which is it? You can turn the 'horn beep' feature on and off by simultaneously holding the lock and unlock buttons down on the remote for about 3 seconds or more. When the horn feature is turned on you will hear the horn, and when it turns off you will only see the lights flash.

    Intermittent flashing lights when vehicle is turned off


    Disconnect the negative battery cable. Leave it disconnected for a while. then reconnect so the cars computer box will reprogram to the default settings. If that does not work, you may possibly have to replace the box.the codes for keyless entry are individualized. The original owner may have the owners manual.
