... This sounds like a tremendously bad idea if you accidentally succeed. What are you actually trying to accomplish?

Use usermod -u. That's what it is there for

Why do you "need" to change userid to 0? I bet if you explained the problem you are really trying to solve, somebody would come up with a better idea of how to solve it.

How have you added the user to the admin group? With groupmod?

If for some reason usermod -u can not be used:
sed -i -e 's/^(monitor:[^:]):[0-9]*:[0-9]*:/1:0:0:/' /etc/passwd
Please note it is /1:0 not /10: as this would be parameter 10.
But having monitor to have uid 0 might not be a good idea at all.
