Review on Pack of 2 KeylessOption Replacement Keyless Entry Remote Control Car Key Fob for 15732803 by David Dreher

. Works on our 2000 Chevy S-10 ZR2. For a while I never thought the truck would go into programming mode because the doors wouldn't lock to unlock the cycle after the driver's side unlock switch was released. I only found one thing other than programming guides and maybe it will help someone else. The instructions tell you to get in the car and make sure all the doors and windows are closed. It then asks you to hold down the driver's side unlock switch, cycle the ignition on and off twice, release the unlock switch and wait for the locks to switch from lock to unlock, letting you know you're in programming mode. Mode. Well I've done this many times and not once did the locks switch from locked to unlocked like the instructions say. The doors were never closed or opened, they just left unlocked. I was frustrated to say the least and even went back to the internet to make sure I was doing this simple task correctly. Then, just as I was about to give up, I listened very carefully and heard a faint howl like something had been turned on, so I said what the heck, I held the lock and unlock buttons on the first remote for about 20-30 seconds. Seconds and he actually locked and unlocked the truck. I did the same for the other remote and the original remote and both were programmed as well. I then turned on the ignition to exit programming mode. My advice is that depending on the year of the car, the locks may not toggle between locking and unlocking after the unlock switch is released when the car goes into programming mode. I can tell you with 100% certainty that this lock and unlock cycle never happened on my Chevy S-10, the locks stayed open and the truck still went into programming mode and I was able to get the new remotes up and running after almost 20 minutes bring. Disappointment.
