How much would it cost to replace the lock?How can I open the rear door of my Toyota Siena Van 2001, which have lock is broken?Depending on the cost of the lock, it shouldn't take more than a half hour to change at the most. Normal shops get about $75- 95 an hour so figure $50 or lass in labor. The cost of the lock can be found out from the dealer if you want the same key. Or if you want to save some money, you can try for a junkyard lock but it will have a different key. You can see if they have a key to go with it or have it rekeyed at the dealer. To open it now, you can take off the interior of the door and pull the rod that opens the door. You can find it after the interior comes off. It will be between the door skin and frame.
