I broke a key off in the lock of a desk drawer. The lock doesn't look easily replaceable, so how can I remove it? I've tried tweezers but they can't get enough of a grip to pull it out.

I had this happen and used a pair of needle nose pliers. I had to buy a set of extra small ones at the store. There is an amazing assortment. I imagine that something like pliers made for electronics would do the trick.

This turned out to be the solution. The hardware store had a pair of needle nose pliers with very fine tips. It was the only thing I could find that could get in there. –  Carey Gregory Nov 23 '12 at 22:36

A locksmith would use a key extraction tool to remove the key.

Well, that would probably do it but it looks pretty expensive. Is there a tool at the local hardware store that would suffice? –  Carey Gregory Nov 19 '12 at 5:29

You can get some cheap lock pick sets I bet for under $20... really all it is is small, sturdy metal tools –  Steven Nov 19 '12 at 13:06
    
Check your local laws on lock pick sets. Some locations consider possession as intent to use a burglary tool (without a locksmith license), so owning them is illegal. –  BMitch Nov 19 '12 at 13:21
    
guns and knives are OK but lock picks are bad.... what a world we live in. –  Steven Nov 19 '12 at 14:28

In the past I've used a thin barbecue skewer to extract broken keys, I also found a set of eyeglass screwdrivers handy as well. It all depends on how deep it broke off of course.

EDIT: How you use the skewer depends on how the key has broken. Keys are commonly made of cast lightweight metals which have a rough texture with lots of pits outcroppings along the break. What you are trying to do is use the point of the skewer to get into one of those and then use the bottom or top of the lock slit as a fulcrum to pry the key out.

Alternatively if you can get the point into the top of the lock above the key you may be able to get the point in front of the rearmost tooth and then use to the top of the lock slit for leverage.

It may be useful to have more than one skewer, thin screwdriver, what have you available and use them in conjunction.

You might be able to finesse it out with the tip of a small pocketknife or a dental pick -- try to get the point against the side of the key remnant and drag it out, using as little pressure as possible. If you can move it even a small amount you may be able to repeat enough times to get it to where you can use tweezers or needle nose pliers.
