gtwhen performing the step of turning the key clockwise in the hole you will have to force it fairly hard and whatever you do don’t stop or turn backwards the crunch sound of the internal lock barrels pairing the first time is normal just keep going until the lock pops open you will ruin the lock if you back off

Seems good quality very quick to key lock is excellent only major thing to note lock comes with very vague instructions on back of package so i can see how people have had issues pairing their vehicles key
