Hey guys quick question, so I change my battery from my key remote and accidentally hit the little chip and come off, so I took it to one of my friends to weld it back , because no one will do this car for new key only land rover , so it opens my door and I put the key to turn the car on and all the lights come on but it won't crank, I see the little alarm red light blinking so the couldn't be the problem , so my question is do I need to reprogram the key or I need a new one?

A

Thanks in advance

 

It would help to know what type of vehicle you're talking about.
