need to get in my room-recommend locksmith for central bangkok(pathumwan)

Locked myself out, live alone and when I go back home from office today, i will need to get in. As it's a condo, the juristic office(besides they don't work on Sundays) doesn't have copy and owner is too far away. I prefer someone who doesn't triple the price when they find out the area and that it's a foreigner. This happened 6 years ago in another condo i was renting. Neighbor called one she had used week (was charged 500 baht) before... when he came out told me 1500 she tried to talk to him but he basically said in Thai want in or I go. I could probably break in and have the lock fixed for cheaper than that.
