Central locking in Volvo V70 models controls door locks, tailgate or luggage compartment lock and the fuel filler flap lock. The electronic functions of central locking are spread out over several control modules, with sensors and actuators connected directly to a control module in the vicinity of their installed location. The central locking remote unit and the central locking control module handle the majority of the functions.

The lock mechanism in each door consists of a latch, an exterior door handle and an inside door lock release handle. Only the driver door (left front in North America) is equipped with a lock cylinder. The exterior door latch is responsible for locking, unlocking and latching the door shut. The latch itself is pretty durable. However, having the electronic lock solenoid integrated in the latch creates some problems. The lock solenoids fail over time, leaving you with a malfunctioning lock. If it is the driver lock, you can still lock and unlock with the key. With other kinds of doors, you may not be so lucky. If you are having a problem with the function of the lock, try cleaning and lubricating the latch. I find this will restore function of the lock from time to time. If I can successfully restore function this way, I still replace the latch to avoid future problems. It is a good test to see if the problem is electrical or mechanical.

There are two micro switches in the latches. When dirty they will stick causing malfunctioning locks. Cleaning and lubricating the latch can bring these back to life.

Keep in mind that when your car was serviced before, parts may have been replaced with different size fasteners used in the replacement. The sizes of the nuts and bolts we give may be different from what you have, so be prepared with different size sockets and wrenches.

Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. If you're working with the electrical system, disconnect the battery before beginning. Always catch fluids in appropriate containers and properly dispose of any fluid waste. Recycle parts, packaging and fluids when possible. Never work on your vehicle if you feel the task is beyond your ability.

Our vehicle may vary slightly from yours as models do change and evolve, as they grow older. If something seems different, let us know and share your info to help other users.

Remove the interior door panel. See our tech article on door panel replacing.

The door latch and door power lock solenoid is replaced as one unit.
Figure 1

The door latch and door power lock solenoid is replaced as one unit. This photo shows the left side front latch (red arrow). This is the latch covered in this tech article. Other doors are similar.

Working at the top outside corner of the door, remove the plastic cover (red arrow) by pulling it straight out.

Remove the door handle Bowden cable (red arrow) from the window regulator by pulling it straight up.

Working at the door latch, disconnect the door lock rod (red arrow) by pulling it straight out of the latch (green arrow).
Figure 4

Working at the door latch, disconnect the door lock rod (red arrow) by pulling it straight out of the latch (green arrow). Pull the lock rod up and through the rubber grommet and out of the way.

Working at the outside edge of the door above the latch, remove the plastic cover (red arrow) by pulling it straight off.

Remove the four T30 Torx door handle fasteners (red arrows) and door latch fasteners (green arrows).

Slide the door handle out of the door about three inches (green arrow).
Figure 7

Slide the door handle out of the door about three inches (green arrow). You can let it hang. It doesn't have to come all the way out.

Then rotate the door latch toward the door skin (red arrow).
Figure 8

Then rotate the door latch toward the door skin (red arrow). This moves it around the window guide rail.

With the latch rotated enough to access the lower electrical connectors disconnect both electrical connectors (red arrows).
Figure 9

With the latch rotated enough to access the lower electrical connectors disconnect both electrical connectors (red arrows). Press the wire retainer and pull the connectors straight off the latch.

Then remove the door latch assembly from the door by rotating the latch as you feed the latch opening out first.

Pull the latch cable out of the latch.
Figure 11

Pull the latch cable out of the latch. Unlock the clip at the bottom (red arrow) and pull the cable (green arrow) straight up to remove it. Then unhook the cable end from the lever (yellow arrow). To install the new latch reverse the order of the steps. When installing the latch, align the lock cylinder rod with the door latch. If you are having trouble aligning the two, use the key in the lock cylinder to rotate the rod while installing the latch. I find this helps to get them to mate. Remember to check the function of the latch before installing the door panel. I suggest closing the latch with a flathead screwdriver while the door is open. Then open it using the cables once you attached them. This will ensure it is working.

To replace the interior door handle, remove the latch and detach the cable from the latch.
Figure 12

To replace the interior door handle, remove the latch and detach the cable from the latch. Then remove the four T25 Torx fasteners (red arrows). Remove the handle from the door and reverse these steps to reinstall.

revbradl Comments: Hi Again Nick, the lights go out when having the door open and using a screwdriver to actuate the latch.

  Followup from the Pelican Staff: OK, so either the latch is worn or the door isn't closing enough to latch it fully. Likely the latch. - Nick at Pelican Parts  
revbradl Comments: Nick, Thank you for interacting with me about this question. I'll test the latching function using a screwdriver soon and report back to you.

  Followup from the Pelican Staff: Thanks. - Nick at Pelican Parts  
revbrad Comments: Hi, thank you for this excellent tutorial. I have an issue with the electrical part of the latch, it often doesn't know the door is closed so the courtesy lights and key chime stay on. I have to slam the door repeatedly until it finally goes off. Is that switch mechanism something I can work on if I take the latch assembly out?

  Followup from the Pelican Staff: If you close door latch using a flathead screwdriver (with door open) does light go out? - Nick at Pelican Parts
