I have a 2005 Spectra that I am having door lock problems. All the doors unlock fine,but when I lock them with the keyless entry or manualy the back left door make a loud grinding noise. It locks but the noise is very loud and isolated to the interior of the door panel.

does your unlock button work in car? If it does, do you have another keyless entry key fob? If so does it work? If you just replaced the battery you can try removing battery and cleaning contacts within remote. I know some of the nissan altimas had the same issue and the only solution was a new key fob. Good Luck

Programming Electronic Door Lock Control System NOTE: The electronic door lock control processor (14B001) erases all previous keyless entry remote transmitter (15K601) from memory when the keyless entry remote transmitters are programmed or reprogrammed. The electronic door lock control processor can store up to four keyless entry remote transmitters in memory.

• To program (or reprogram) keyless entry remote transmitter into the electronic door lock control processor, perform the following steps:

1. Turn ignition switch to the RUN position and momentarily short the two terminals of the program connector taped to the wire assembly and located behind the glove compartment. All doors should lock and then unlock. Remove shorting pin.
   

1. Press any button on keyless entry remote transmitter. All doors should lock and then unlock to verify the keyless entry remote transmitter has been programmed. If door locks do not respond, press button again (up to three times maximum with the same keyless entry remote transmitter).
   

1. Repeat the above step to program additional keyless entry remote transmitters into the electronic door lock control processor (up to four keyless entry remote transmitters maximum).
   

1. Turn ignition switch OFF. All doors should lock and then unlock.
   

1. Check operation.

To program the transmitters, perform the following procedure while seated in the vehicle driver's seat:

Close all the vehicle doors.
Remove the ignition key from the ignition lock cylinder.
Press and hold unlock on the door lock switch.
Important: To successfully enter the keyless entry programming/diagnostic mode, steps 4 through 6 must be completed within 25 seconds of pressing the door unlock switch.

While holding the door lock switch in the unlock position, insert and remove the ignition key twice. Do not rotate the ignition lock cylinder.
Insert the ignition key a third time leaving the key in the ignition lock cylinder. The ignition must remain in the LOCK position for the rest of the procedure.
Release the door lock switch. The chime will sound three chimes to signal that transmitter programming/diagnostic mode is active.
Press and hold the lock and unlock buttons at the same time on the keyless entry transmitter for approximately 4 seconds. The chime will sound two times to signal that the transmitter has been programmed successfully.
To exit the transmitter programming/diagnostic mode perform either of the following:
• Turn the ignition switch to the RUN position.

• Remove the ignition key from the ignition switch

Sounds like they disconnected your battery when they were working on your car. Your radio probably requires an unlock code to get it to work again which you'll have to get from a dealership with proof that the car is yours.

They key fob will also have to be reset.

1. Close all the vehicle doors.
2. Insert the ignition key into the ignition lock cylinder.
3. Press and hold the door unlock switch.
4. While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
5. Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
6. Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.
7. Turn the ignition switch to the On position in order to exit the keyless entry transmitter programming mode.
8. Operate the transmitter functions in order to verify correct system operation.

Unfortunately the actuators are bad. You could try removing the door panels and disconnect one actuator at a time and possibly only have a couple bad but it is common to have more than on go bad. I hope this helps. Good luck.

Factory keyless?

The keyless entry is designed to work with the doors closed (closed - not locked). If the door ajar sensor thinks the door is open the keyless entry is disabled. When you manually lock the door it might tighten the door just enough to activate the keyless entry. I would try slamming all the doors closed and then see if the keyless entry works. If it still wont work have the wiring checked on the front door lock.

Lock all the doors from the inside (with all the doors closed), unlock your driver's door by manually lifting the lock, then press it back down after you are out - this will prevent the alarm from sounding when you use the key to unlock the door.
