Remote For GMC Cadillac Chevrolet Hummer Pontiac Saturn:


GM Part Numbers: 21997127

Condition: Brand New Aftermarket (No Logo)

Brand: Avicero

GM's current part number is 21997127.  Your old remote has one of these discontinued numbers: 15186200, 15186201, 15132197, 15132198, 10377295, 22730827, and 15186203.  The FCC ID is LHJ011. GM has remade this remote many times. They originally had memory #1 and #2 remotes. The purpose was for vehicles with seat memory. In reality it was ridiculous because the order that you program them determines which is #1 and #2. The numbers on the back were just for reference. In 2006 GM decided to discontinue using #1 and #2 and they started making un-numbered remotes. GM's current part number for this remote is 21997127. If you go to a GM dealer parts department you will get the new number remote no matter what remote you have now. All the remotes with the part numbers listed above are identical inside and in function so we mix them together.

Programming Procedure:

  • For 2005-2006 Equinox, 2006 Torrent, 2004-2007 Vue.

Since your vehicle is not onboard programmable or you need key cutting, you will need a dealer or automotive locksmith to program the vehicle to accept the replacement remote or key or to cut a key. Please use an automotive locksmith rather than the dealer. You are likely to get a better service for a more reasonable price. Locksmiths make their prices based on their local market as well as the cost of the equipment used for you cutting or programming.

  • For 2003-2006 Escalade, 2003-2006 Avalanche, 2003-2007 Silverado, 2003-2006 Suburban, 2003-2006 Tahoe, 2003-2006 Sierra, 2003-2006 Yukon, 2003-2007 H2.

IMPORTANT: Before entering programming mode, have in possession all of the transmitters you will be using on the vehicle. Once you program the transmitter, all previous codes will be erased from the memory. The other transmitters will not be functional until you program the transmitters again.

1. Close all vehicle doors, windows closed, wait for dome light to go off.
2. Insert the key into the 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 fairly rapid succession.
5. Turn the ignition switch to the ON position (as far as you can go without starting the engine).
6. Turn the ignition switch to the OFF position.
7. Turn the ignition switch to the ON position.
8. Turn the ignition switch to the OFF position.
9. Release the power unlock button on the door panel. The vehicle will lock and unlock the doors automatically.
10.Hold down the LOCK and UNLOCK buttons on the transmitter simultaneously until the door locks and unlocks. This step may take up to 30 seconds.
11.Repeat step 10 for each additional transmitter (including any existing transmitters).
12.Turn the ignition switch to the ON position in order to exit the transmitter programming mode.

Return Policy


At RAK we make returns as easy as possible. Our mission is to provide you with the best products and the best service in the industry. We understand that sometimes, customers change their minds about products that they order or simply do not need them anymore. We also know that customers are cautious about Return Policies since they are often tricky and misleading. Our goal is to make the return or exchange process trustworthy and as simple as 1-2-3.


If for any reason you are not completely satisfied with your purchase, you may return the item within 30 days of delivery of your order. The following rules apply:

Products must be in the same condition we sent it in. If the condition isn't in the same condition that we sent to you, then the refund amount will be less due to our cost to restore or refurbish the item. If it's not possible to restore or refurbish then the refund would be the value we could sell it for in the condition it is now in minus 20%. If you place a "Special Order" with us then there would be a 40% restocking fee.

Shipping Fees are non-refundable.

All returns must be made by signing in, going to MY ACCOUNT, clicking order history, finding the order, click Return this item.There are few non-returnable products & services that may be offered on our website. It will indicate clearly in the product description if a different return policy applies.

Order cancellations can only be requested prior to shipment.


To return a product, you must first request a Return Merchandise Authorization (RMA) that is located in the MY ACCOUNT section next to each order item that you want to return. Once you've selected the items to return and the reason, you will be given return instructions.


There are 2 ways you can go about exchanging a product:

Option 1 (Slower) - Use the standard return procedure to request an RMA for the part you need exchanged. In your request please specify the exact item(s) you would like to exchange to. Upon receipt of your returned product we will process an exchange and ship the new part. If there is a difference in the price, you will be either refunded or charged the difference.

Option 2 (Faster) - Order the new part over the phone and request to include a prepaid label to send back the first purchase for refund.


We all know that accidents happen sometimes. If your product(s) will arrive defective, damaged, or simply incorrect, please contact our customer service department as soon as possible. Please do not attempt to use or install the part! We will send you a replacement part and provide you with a prepaid return label to return the defective part. Product(s) must be returned to us within 30 days. If the damage was caused by a shipping courier, we will schedule a damage pick up by the courier.


A tracking number is provided with every order you place. Once the carrier’s status shows the package has been delivered we are not responsible for replacement orders!


When you request a cancellation of an order or a part it may take up to 24 business hours to process your cancellation claim. This process may involve voiding orders in computer systems, removing items from backorder logs, having operations personnel pull items from production schedules and sometimes stopping orders at the shipping dock. Also note that sometimes products ship more quickly than expected, so we recommend that you do not purchase alternative products until receiving final confirmation of your cancellation.


After we accept your return, you will be issued a refund via the same payment method as you had originally used to place the order. The refund amount will be composed of the original purchase price minus shipping charges. You will be sent an email confirming receipt of the return and your credit. Please allow an additional 5-7 days for the credit to appear on your account.

Remote works 100% perfect on my 2003 Chevrolet Silverado 1500 Z 71 off road truck. Turns on the lights inside and outside. Second press unlocks all doors. Press the horn button an horn works too. Programed it in about 30 seconds. Even works 60 feet away from inside the house.

I honestly didn't think this was going to work! But, I pulled it out of the box, sat in my car and did the gyrations as explained on the instructions, and BAM! Works like a champ! I don't know if it'll survive a turn in the washer like the OEM, but it might. My wife is super happy to have a fob again and I'm super happy to not have to go to the dealer and get ripped!

Cheap, Cheerful and works like a champ!
by Valued Customer on June 13, 2012

Cheap and Cheerful. Programmed in first time using the directions on the website. I tested the range and it goes farther than the OEM it replaced (of course it has what I suspect is a new battery and the old one had a used battery.) So if your remote is broke/damaged/rubber buttons have collapsed I recommend this replacement FOB. Just remember that you have to have ALL of your remote FOBs with you that you want to program when you add a new one, even ones that are already working.

This replaced my only stock keyfob, which only worked about 10% of the time to unlock. I tried cleaning the inside, even replacing the shell... Then this beauty, and in less than 5 minutes I had a 100% working keyfob.

Worked great. My old one had to be pushed hard and the rubber on the unlock button had cracked. Only took a few minutes to connect this new one to my 2003 Silverado. Comes with battery already installed. I opened it up thinking I needed to install one before I realized it already has one.
