Why did nobody ever cut out the chip?

So, i just watch the first and second movie, and i'm watching the third movie right now. And a thought just came to me, why has nobody ever cut out their tag/chip from the back of their neck?

They should know it’s there, and even though it doesn’t look like it can be used for tracking purposes, wouldn’t it be smart to still get rid of it so it can’t be scan? Like in the third movie, Thomas and the gang are in a big crowd of people, but a drone overhead is able to scan his chip and find him, which let WICKED know he’s there

I apologize if this question has been asked before, I did a search and I couldn’t find anybody talking about it.

Lmao, never mind. 5 minutes later and they’re now cutting it out. Crazy timing
