the ignition key barrel has to be removed by putting the key inbetween the a and d settings to allow tabs to be pushed in.....

not sure about the glovebox lock but i imagine its something similar.

found this on an other forum

The glovebox door is helt on by 2 plastic pegs on the bottom remove the carpeted part of trim underneath and there easyish to get at. Then the lock can be taken apart with a flathead screwdriver so the lock internal can be removed and swapped into a new lock. I did this myself afew years back so not 100% on each step but its not very hard. Trickyist part was getting the spring to stay still on the lock so it springs back when you turn it to open
