I ordered a pair of key FOBs for my 2010 Corolla from extra-parts and have had ZERO luck with those. After striking out with trying to program these based upon youtube tutorials, I finally took them to a locksmith and he likewise was unable to successfully program for the door locks, car finder (horn), etc. They sent me a replacement set of transponder modules, which goes into the plastic head of the key, but those exhibited the same incompatibility issue and not recognized by the car's security system once the car was in the receptive programming mode (which you enter into by a sequence of steps by inserting the key into the ignition, open and closing of the door, etc. I finally ordered an OEM key of the same model number (GQ4-29T) from a different ebay seller and it worked just fine! I returned extra-parts keys back to them, but still had to fight to get the $34 back through my credit card company. They never even remotely considered compensating me for the $50 locksmith fee.
