I actually did this yesterday, replacing my inner door handles, the first lock tab i broke, 2nd one i got off but scarred it, 3rd one, very gently with a razor blade, on the left side of the little red tab, insert the razor blade, after a little while it will pop forward, allowing you to lit the tab up and off, and get to the screw behind it. Good luck, and be prepared to go to the wreckers afterwards if your fussy about chips or scratches out of them. And just another thing to note, when you do go to pul your door trim off, it's held on by these little blue screw plugs, they will pop out alright if you pull on them, but i found on the first trim, 3 of them broke. So on the rest of them, i just popped one out, and then went around with a set of needle nose pliers, and gently pulled them out,time comsuming, but nessacary if you want your trim to fit back on tightly. You'll see what i mean after you pull the first trim off, and then go to re-fit it afterwards.
