On average, you can expect to pay between $200 and $300 for a car door lock replacement, with the exact cost depending on your vehicle’s make and model.
When the locking/unlocking mechanism on your car door stops working, it usually means that the door lock cylinder will need to be replaced in its entirety, even if only a small component stops working correctly. A new car door lock can cost between $140 to $150.
If you take your vehicle to a mechanic for the replacement— as replacing a car door lock yourself can be challenging—expect labor costs to fall anywhere between $60 and $80.
