Mercedes-Benz Rear Door Locks by Part Number
| Door | Mercedes part number |
|---|---|
| Rear left (passenger side) | A2047303935 |
| Rear right (driver side) | See product page for the part number |
| Rear left & right pair | Both rear locks together |
Mercedes part numbers start with the model series the part was first made for, and the same lock is often used on several models. The part number on your old lock is the safest way to match. If you're not sure, send us your reg.
How to Choose
- Confirm it's a rear door. These locks are for rear doors only.
- Pick the side: right (driver side on UK cars) or left (passenger side), or the pair if both rear locks have failed.
- Match the part number printed on the old lock's label.
- Not sure? Send our team your registration or VIN, or a photo of the label, for a free fitment check.

Mercedes-Benz Door Lock FAQs
Where is the part number on a Mercedes door lock?
It's on a label on the lock body and usually starts with "A" followed by ten digits, for example A2047303935. You'll need to remove the door card to see it, or send us your reg and we'll check for you.
Do you have Mercedes front door locks?
This collection currently has rear door locks only. Contact our team with your registration or VIN and we'll check what else we can supply.
Is the actuator separate from the latch?
On these Mercedes rear doors the motor is built into the lock unit, so the complete unit is replaced.
