even if you have both hands, if you don't have the key or something to cut the chain you can't free yourself. That's why handcuffs are used: to block hands.
well I'm good at getting out of handcuffs if only one hand is cuffed. Ever heard of the "sacrificial nail" technique? I'd rather lose my nails then stay handcuffed lol. And Lee also said in episode 3 that he knows how to pick locks (he lied to Kenny but told the truth to Clementine)
He's not gonna get out of those handcuffs for a while if he turns. He'd have to wait until his arm was rotted enough to come off, like what happens to the security guard if you cuff him instead. Plus, another living person would have to come along before Walker Lee actually did anything. Walkers don't wildly swing their arms around unless they sense food nearby, and I don't think there are many people left in Savannah aside from Molly by the time Ep5 ends.

You only need one hand cuffed to be restrained to an object.
Seriously...
What if zombie Lee does know how? It'd be surprising to meet his zombie in season 2 if Clem doesn't kill him.
If you have both arms, the one you got bit in is numb and he can't move it and Clem cuffs your other, working, arm.
Lee's dying, he has no energy because of that, Lee dies, Lee turns, Walker Lee has energy.
Really, if everyone who didn't had energy before dying wouldn't had been a problem, the zombie apocalypse would had been a lot less dangerous.
