I just git a 2003 chevy impala the remote works to lock and unlock the car but i cant get thr alarm to chirp .the doors lock but the alarm doesnt come on.can anyone help.

Git the fob workn. Vehicle battery may be old or electrical system may not b charging the modules. Car shud be scand

if stock system fob is a few bucks online and did you retest the battery in fob new doesnt mean free from defects also if auto start dealer needs to program fob ---now if stock when enter vehicle have a minute or two to put key into ignition and turn or before alarm goes off --but when you do it it resets and turns the alarm off

first replace the batteries in the remote . Also try manually locking the doors and use the key to open it .Sometimes that works. good luck

Use the key to lock and unlock door or truck, this is the same as using the remote. go to a door or the trunk and lock and unlock and then try to start the car, let me know the outcome. good day.

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.

new remote for 2005 Imprezas.
This is not the same remote as the 05 Legacy/Outback remote which also has truck/gate release on the front and a red panic button on the back.
Lock: press Lock button for 2 seconds or so to lock car, and arm optional security system. The car with chirp once and turn signals flash for locked, 5 short chirps and signal flashes if any door is not fully closed. The dome light goes on for 15 seconds and ignition key ring (if present) will light for 30 seconds when unlocked.
Unlock: press unlock one time for driver's door, press again within 5 seconds to unlock all doors inkling rear gate (wagon). The system does not open the trunk.
Panic mode: press and hold lock button for approx. 3-4 seconds to activate Panic mode. I panic model the horn honks and turn signals flash until either the lock or unlock button is pushed again.
Finder mode: Press lock button 3 times within 5 seconds to activate Vehicle Finder mode. The horn will honk once and the turn signals will flash 3 times
Distance: works within approx. 30 feet depending on battery strength, nearby concrete walls and etc.
Audible Chirp On-Off: the system will chirp when locked or unlocked. To turn OFF the chirps, unlock the door and then push both lock and unlock buttons at the exact same time for 2+ seconds. There will be 2 chirps indicating the the audible is off. To turn the chirp back on, repeat the process and the system will chirp one time when it is back on.
Battery: as the battery ages it will only work as you get closer to the car. When a battery is replaced, the transmitter must be re-synchronized with the Keyless control unit. To synchronize, press the lock or unlock button 6 times.
Programming: 4 codes may be programmed.
Sit in driver's seat and unlock all doors. Open and close the driver's door
Turn the ignition key from LOCK to ON position 10 times within 15 seconds. Be sure to stop at both lock and on. The horn will HONK once to indicate transmitter programming mode is activated. Leave key in LOCK position and don't remove it from ignition.
You now have 45 seconds to complete the programming as below.
Open and close driver's door again.
Push either lock or unlock button on the remote you want to program. The horn will honk 2 times when successful.
To continue and program other remotes at the same time: open and close the driver's door and push lock or unlock on the remote. The driver's door must be opened and closed between each remote you want to program.
Done programming? remove the key from the ignition and the horn will honk 3 times.
DELETE old codes? Reprogram 4 times, it will overwrite old codes.
Alarm Security System: optional on all models. When locked there is one chirp (can be turned off, see above), the turn signals will flash and the red 'security' light will start to flash once every 2 seconds except for STi which flashes twice every 2 seconds.
There will be 5 chirps if a door, hood, and trunk or gate is not fully closed
You can also arm the system by using the power lock button on the driver or passenger door as you get out of the car and then closing the door behind you.
Disarm the system: push unlock for 2 seconds
Lost remote, alarm activated? When you can't use a remote to turn off the system: open the door with a key or try to start the car and the horn will start to honk. Turn the key on-off 3 times within 5 seconds and the alarm will go off and you can start the car. It's simple!
VALET mode: To set valet mode or just to disable the security alarm system: 1. unlock all doors 2. physically open the driver's door 3. hold the UNLOCK button on remote for 2+ seconds. The red 'security' light will then flash 2 times a second until the car is turned on.
System has been Tripped (except for STi): if you unlock the door with the remote and it chirps the signal light flash 4 times, the system has been triggered;
Identification mode: To find out what happened and why the system was triggered:
Open and drivers door, leave it open. Turn ignition key from LOCK to ON 2 times and then leave in LOCK position.
Tripped code: 1 security light flash: a door has been opened, 3 flashes when the impact sensor was triggered, 4 flashes when the ignition was messed with or battery disconnected

Do the locks work when using the interior lock buttons? If so, then you probably have to have the car dealer reprogram you remotes

I have same problem with Malibu 2003,use the remote to lock the car then unlock it and start the car again.if this won't work probably it's the theft alarm stopping the engine from starting

this happened to me and it drove me crazy for a few days. check that the hood is closed tightly. its held shut for the most part by a peice of metal with a screw on one side, a spring around it, and a nub looking shape that fits into the locking device above the bumper. When i finally checked my hood, the entire bit of metal had come unscrewed and was stuck in the locking device, leaving my hood held shut only by the safety clamp. remove it from the locking part and screw it back into the hood, closing it a few times to find the right distance to screw it in. lock your car and hear that chirp, that should fix it

if thats not the case then check that all of the doors are closed nice and tight... if the doors lock but the audible alarm is not armed then that is most likely the case

Disconnect the battery from your car (negative cable only) overnight. Make sure you have your radio reset code before doing so.

Then reconnect after 10 hours, and make sure you have remote handy as alarm may go off. Then if that doesnt fix it, go to driver door, then insert master key, pull up on handle first all the way and hold it. Then turn the key slowly all the way so the doors unlock and continue turning the key. This will reset the central locking system as yours may have gotton stuck. then remove key let go of handle, open door and try to lock and unlock doors from switch inside car.

Then try remote. It should work, this is what the dealer will do and charge you about $350...if it doesnt work order a new remote b/c yours may have become damaged by liquid or dropping?

Have a great day,

Thanks,

Mark
