Question about 2004 Chevrolet TrailBlazer

1 Answer

My key does not unlock my door anymore. I can only unlock my vehicle with the remote. I'm afraid I won't be able to get into my vehicle if I misplace my remote! Any suggestions? The headlight went out on my vehicle, what is the light bulb number I need to replace it?

As for the door lock, try spraying a little white lithium grease in the key hole and insert your key and rapidly move in and out to get the tumblers loose again and get it working. now, as for the head light, just go to your local parts store and they will gladly help you get the right bulb for you and can even help you replace it if needed.

LOCKING AND UNLOCKING
You can use the power door lock control or the remote control to lock and unlock your doors and tailgate.See Tailgate Lock.
Power Door Locks
The power door lock control is on the driver and front passenger door panels.

AUnlock.
BLock. Remote Control
You can use the remote control at any time your vehicle is not running.
Unlocking the Vehicle (Two-Stage Unlock)
Press the button to unlock the driver door. Press the button again within three seconds to unlock all doors.The direction indicators flash. The direction indicators flash twice to confirm the change. The unlocking mode applies to the remote control, keyless entry keypad and intelligent access.
Press and hold both the lock and unlock buttons on the remote control for four seconds to disable or enable two-stage unlocking. Disabling two-stage unlocking allows your entire vehicle to unlock with one press of the button.
Intelligent access at the driver door unlocks your entire vehicle when you disable two-stage unlocking.
Locking the Vehicle
Press the button to lock all doors.The direction indicators flash.
Press the button again within three seconds to confirm that all the doors are closed.The doors lock again, the horn sounds and the direction indicators flash if all the doors are closed.
Mislock
If any door is open, or if the hood is open on vehicles with an anti-theft alarm or remote start, the horn sounds twice and the direction indicators do not flash.
Activating Intelligent Access
General Information
You can unlock and lock the vehicle without taking the keys out of your pocket or purse when your intelligent access key is within 3 ft (1 m) of your vehicle. Intelligent access uses a sensor on the back of the door handle for unlocking and a separate sensor on the face of each door handle for locking.
The system does not function if:
  • Your vehicle battery has no charge.
  • The key battery has no charge.
  • The key frequencies are jammed.
Note: The system may not function if the key is close to metal objects or electronic devices, for example keys or a cell phone.
Note: If the system does not function, use the key blade to lock and unlock your vehicle. See Remote Control.
Unlocking Using Intelligent Access
With your intelligent access key within 3 ft (1 m) of your vehicle, touch the unlock sensor on the back of the door handle for a brief period and then pull on the door handle to unlock, being careful to not touch the lock sensor at the same time or pulling the door handle too quickly. The intelligent access system requires a brief delay to authenticate your intelligent access key fob.
Locking Using Intelligent Access
With your intelligent access key within 3 ft (1 m) of your vehicle, touch the outer door handle lock sensor for approximately one second to lock, being careful to not touch the unlock sensor on the back of the door handle at the same time. After locking, you can immediately pull on the door handle to confirm locking occurred without inadvertently unlocking.
Note: Do not use the outside door handle as a roof cargo strap.
At the Electronic Tailgate (If Equipped)
Press the exterior tailgate release button inside of the tailgate handle. The tailgate unlocks and opens. See Electronic Tailgate.
Smart Unlock
This feature helps to prevent you from locking your intelligent access key inside your vehicle's passenger compartment or rear cargo area.
If you leave your key in the ignition, when you open the driver door and lock your vehicle with the power door lock control, the doors lock then unlock.
You can still lock your vehicle with the key in the ignition by:
  • Using the manual lock on the inside of the door.
  • Locking the driver door with a key.
  • Using the keyless entry keypad.
  • Using the lock button on the remote control.
Smart Unlocks for Intelligent Access Keys
This feature helps to prevent you from locking your intelligent access key inside your vehicle's passenger compartment or rear cargo area.
When you lock your vehicle using the power door lock control (with the door open, vehicle in park and ignition off), your vehicle searches for an intelligent access key in the passenger compartment after you close the door. If your vehicle finds a key, all of the doors immediately unlock.
In order to override the smart unlock feature and intentionally lock the intelligent access key inside your vehicle, you can lock your vehicle after all doors are closed by using the keyless entry keypad, pressing the lock button on another intelligent access key or touching the locking area on the handle with another intelligent access key in your hand.
When you open one of the front doors and lock your vehicle using the power door lock control, all doors lock then unlock if the ignition is on.
Autolock
Autolock locks all the doors when:
  • All doors are closed.
  • The ignition is on.
  • You shift into any gear putting your vehicle in motion.
  • Your vehicle reaches a speed greater than 12 mph (20 km/h).
Autolock repeats when:
  • You open then close any door while the ignition is on and your vehicle speed is 9 mph (15 km/h) or lower.
  • Your vehicle reaches a speed greater than 12 mph (20 km/h).
Autounlock
Autounlock unlocks all the doors when:
  • The ignition is on, all the doors are closed, and your vehicle has been moving at a speed greater than 12 mph (20 km/h).
  • Your vehicle comes to a stop and you switch the ignition off or to the accessory position.
  • You open the driver door within 10 minutes of switching the ignition off or to accessory.
Note: The doors do not autounlock if you electronically lock your vehicle after you switch the ignition off and before you open the driver door.
Enabling or Disabling Autounlock
You can enable or disable the autounlock feature in the information display or an authorized dealer can do it for you. See General Information.
Illuminated Entry
The interior lamps and select exterior lamps illuminate when you unlock the doors with the remote entry system.
The illuminated entry system turns off the lights if:
  • The ignition is on.
  • You press the remote control lock button.
  • After 25 seconds of illumination.
The dome lamp does not turn on if the control is set to the off position.
The lights do not turn off if:
  • You switch them on with the dimmer control.
  • Any door is open.
Battery Saver
The battery saver turns off the interior lamps 30 minutes after you switch off the ignition if a door is open and the dome lamp switch is on. It turns off the interior lamps after 10 minutes if the dome lamp switch is off.
Accessory Mode Battery Saver for Intelligent Access Keys (If Equipped)
If you leave the ignition on after leaving your vehicle, it turns off 15 minutes after you close all of the doors.

Wireless Key Remote door & trunk opener won't work with trunk anymore


When you press the trunk open button, do you hear any "release" noise come from the trunk area? The issue may be a bad battery in the key fob OR there could be an issue with the transmitter located inside the vehicle. Do the doors lock and unlock properly? is the vehicle equipped with security or immobilizer? please advise

The doors will not lock or unlock from the door but will from the remote?


The title suggest the door won't unlock unless the remote is used but during the summer it was the inverse. If while inside the car the doors will not lock or unlock from the door but will from the remote then you have a faulty switch.If while outside the car the key turns while in the lock but the door won't lock or unlock then the linkage at the end of the lock is faulty. You'll need to remove the door inside plate to check this.

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

My door locks wont stay locked when put in the locked position


Many Chrysler vehicles won't let you lock your keys in. If locked from the inside, or locked before closed, the doors unlock upon closing. If you don't have a remote, you'll have to lock the doors with the key after you close them.

Neither of our remotes would unlock our doors on our 2003 Silverado Z71 the other day. So we tried by unlocking it with the key. That did'nt work either. Finally, we put the key in the lock and waited for...


TRY Relearning the remotes. to do this get in vehicle with doors closed hold the unlock button down on drivers door while you cut key on and off two or three times you should hear locks cycle and horn chirp. let go of unlock button and hold both lock and unlock button down on one key fob for 15 seconds or so you will see locks cycle move to next remote and do same. then cut key on to exit learn mode. as far as door not unlocking with key this is a problem with lock cylinder most likely.
