The Mercedes A Class 180 is a mid-size sport utility coupe. The car features a remote that is used to unlock and lock the doors and boot. The boot can be opened from outside the car using the ignition key or the remote and can be opened from inside the vehicle using the boot release button. The car also showcases a remote boot release lockout component that can be enabled to prevent people from gaining access to the boot and any valuables stored there. Troubleshoot a boot area that won't open by focusing on the key remote control and the boot lockout feature.
Spray the lubricant into the opening of the boot's lock in an attempt to unlock the boot. Place the key into the keyhole and turn to the left and right to release the boot. Push the boot button within the key remote to set the boot free. Press the boot release button positioned inside the car on the driver's door.
Check the remote boot area release lockout feature. This particular switch is located on the side of the boot lid within the boot lid attachment. Turn the release lockout feature to the "Off" position; ensure that you keep the switch in the off position so that the boot panel can open.
Check to see if the remote's battery needs to be replaced. Use a flathead screwdriver to separate the top half from the bottom half of the remote. Remove the battery from the compartment and change it with a 3-volt CR2032 or equivalent battery. Place the two halves of the remote back together and snap them into place.
Look at the distance from which you are utilising the key remote. The remote works from three to 30 paces away. You may need to move a bit closer during bitter or snowy weather.
Check the Mercedes boot for large items that may be blocking the remote's signal and move them out of the way. Walk a few steps to the side or try holding the remote up higher when unlocking from an angle.
Fixing boot lock
Remove the rear seats that are blocking the trunk's opening to the vehicle. There is normally a small latch at the back of one headrest or next to the side of the seat that will let you take out the seat.
Crawl into the boot and find the locking mechanism that keeps the boot closed. Use a torch to illuminate the boot so you can see what you are doing.
Open up the boot latch by inserting the flat tip of the screwdriver into the opening closest to the lower edge of the mechanism. Jiggle the screwdriver around until it catches on a latch that can be moved to open up the boot.
Remove the fasteners from the inside of the boot-area door by taking out screws while holding it into position. The mechanism will stay connected via the wires of the car, so pull the insert plugs apart to remove them from the automobile.
Find the edge of the locking mechanism that shines and is not firmly attached. It will be a small bit of plastic that hooks onto the cord so that you can push and tug it when inspecting the lock.
Join the plastic part securely to the framework of the locking mechanism using superglue. Let the piece dry out until the connection is protected and solid.
Reconnect the wires and the cord to secure it in the exact same way each one was connected before you took them out. Use the screws to secure the system onto the boot door.
See your Mercedes dealer for repairs if none of the methods described works. If your Mercedes latches are faulty then the boot release can also be defective.
