Does it lock an unlock the doors ? How did you program the transmitter ? Like this ?
Important: Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle.
There are 3 methods for programming transmitters, which are listed below as methods 1-3. Up to 4 transmitters may be programmed to the passenger door module (PDM). Each programmed transmitter is given a position of #1-#4 in the PDM memory.
Method 1 - No Tools Required, Program All Transmitters
Important: All transmitters which are to be recognized by the PDM must be programmed in a single programming sequence. When using this program method, all previously programmed transmitters will be erased upon the receipt of the programming signal from the first transmitter.
The order in which the transmitters are programmed will determine its numbering position within the PDM memory. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. The number stamped on the transmitter case is for reference only; #2 can be programmed as #1, or vice versa. Additional unnumbered transmitters are also available.
Close all the vehicle doors.
Insert the ignition key into the ignition lock cylinder.
Press and hold the door unlock switch.
While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.
Release the door unlock switch. The doors will lock and unlock to confirm the program mode.
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.
Repeat the previous step to program up to 4 transmitters.
Turn the ignition switch to the RUN position in order to exit the keyless entry transmitter programming mode.
Operate the transmitter functions in order to verify correct system operation.

Testimonial: "Yes it locks and unlocks. Now it just won’t start."

    The best advice i can give is have a qualified repair shop hook up a factory or profession scanner an check data inputs from the ignition switch to the BCM - body control module . Everything on your vehicle is electronically controlled . Or have a mobile lock smith that is license to do anti-theft system problems .

SOURCE: chevy avalanche will not start

The battery connection to the starter may not be good. Loosen the cable and re-tighten. Check the starter relay, it should have 2 cables, 1 wire. it will consist of 1 to starter, 1 from battery and 1 the wire is the signal wire from the ignition. the contacts in the relay may be gone. It's usually mounted on the firewall and close to the battery. $15+ for the part, and easily replaced. his will definitely keep you sater from turning over.

SOURCE: 2002 Chevy Avalanche. Truck will not

Do a bench test on the starter. Remove starter, hook up a ground cable to starter, and positive to two prongs on starter and it should spin. You can do this in vechile too but not suggested due to risk of injury. If it doesn't spin, probally a solenoid or the starter it self. Unlikely but possible.

SOURCE: 1999 Chevy silverado z71trying to program a new key fob

Use this procedure for New Body Style.
1. Close all doors
2. Insert key into ignition
3. Hold down the power UNLOCK button on the driver's door panel, continue to hold down
until instructed to release in step 9.

4. Perform steps 5 through 8 in a fairly rapid succession.
5. Turn the ignition to the ON position (as far as you can go without starting the engine.)
6. Turn the ignition to the OFF position.
7. Turn the ignition to the ON position (as far as you can go without starting the engine.)
8. Turn the ignition to the OFF position.
9. Release the power UNLOCK button on the door panel. The vehicle should respond by
door locks locking and unlocking automatically. (If locks do not cycle after you let go,
not before you let go of the unlock button, then the vehicle has not entered programming
mode and you must start procedure over. Remove key from ignition, open drivers door
and return to step 1 ). If the locks do cycle automatically then proceed to step 10.

10. Hold down the LOCK and UNLOCK buttons on the remote until the doors lock and
unlock. This may take up to 30 seconds.

11. Repeat step 10 NOW for each additional remote. (Including any existing remotes).
12. Turn the ignition to the ON position to exit the programming mode.
13. Test remote(s).

Lost set of keys, alarm was on car locked. Found spare key only, it will open door, alarm goes off, but the key won't start engine. It will turn in ignition, but dead! It's a Chevy HHR 2006! HELP

Close the doors. Lock the doors using the buttons on the key fob. Use the fob to again unlock the doors. The key should then work the ignition. If this will not work, you will have to tow your vehicle to the dealer and buy a new key and/or fob and have it programmed to the vehicle.

The battery died on my 2003 Chevy Monte Carlo and after the first time I jumped it and drove it around a little to try and charge the battery, the Security light came on. After I parked it and turned it...

Im pretty knowledgable in the whole SECURITY light issue... I dont think this could cause the door lock to not work correctly, but anything is possible. Newer cars are wound up pretty tight. Here is a link to help understand how the security works.
http://vatspasslockpasskeysecurityhelp.yolasite.com/

I'd go ahead and do a "security relearn" on you car. It might help if that is what caused the door issue.
Turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) Turn back your key to regular position and check the door lock. May have to do this process 3x

Chevy Avalanche won't start

If you're getting no power at all when you turn the key to start, try disconnecting the battery and then hook it back up. Chevy has had some problems with an ignition relay solenoid that's mounted under the driver's side dash. Disconnecting power could reset the switch....If that seems to be it, a replacement is around $250. at a chevy dlrshp.
