I have a 1999 blazer and I have to hit the unlock button on my Keyfob before it allows me to start my truck. For example I keep the key fob in my truck ill unlock my door with my key and I have to hit unlock on my Keyfob for my truck to start it's annoying. If I don't hit unlock on the Keyfob the truck won't start and it won't even crank. Is there anyway to delete this? Anybody else ever deal with this? This is my third Blazer and I've never had to do this and I can't find info on it anywhere.

Yes it seems to be the factory setup, and glovebox code isn't there idk if it was removed at some time or what. Keyfob works flawlessly. Key fob key chain loop is broke and won't stay on my key ring. I also go to the lake alot and if I loose my Keyfob or drop it in the water or anything I'm screwed lol. I actually keep an extra battery with the fob Inside my truck Incase the battery dies. There is also some sort of time out, I have about 30 seconds to start my vehicle after the unlock button is pressed if it's not started in that time I have to hit it again for my truck to start. Can I delete the whole Keyless entry ordeal? Or delete the theft protocol all together?
