How to Disable a Nissan Almera Alarm

Updated February 21, 2017

The Nissan Almera is the European version of the Nissan car that was distributed under the Pulsar name in many countries. The Almera comes standard with a passive alarm system that is engaged when you remove the key from the ignition and lock the driver's side door. You may want to disable the Nissan Almera alarm for may reasons, one being that it is more pleasant to do maintenance on the Almera without the alarm going off all the time. The process to disable a passive alarm is simple. You can turn it off in 20 minutes.

Insert your ignition key and turn it to the "On" position, but do not start the car. This will turn the alarm system off.

Open the bonnet of your Almera and remove the fuse box cover. The fuse box is located on the driver's side of the car attached to the firewall (the back wall of the engine compartment). The box cover is attached with a screw that you can undo by hand as it has a knob rather than a slotted head.

Locate the fuse for the alarm system. Use the diagram attached to the inside of the box cover to locate the 10a fuse in position no. 12. This is the fuse you want to take out.

Pinch the fuse in the end of the fuse puller and pull it out. Wait 15 minutes before turning the ignition to the "Off" position (to allow stored power in the alarm system to dissipate). The alarm is now disabled.


Use only the original ignition key to start your Almera if you have removed and replaced the fuse for the alarm system. The Dongle unit (the name of the electronic unit that passes instructions to the alarm system) will need to reinitialize the alarm and it will read the code from the original key. A copy of the key will not have that code.


Do not disconnect the Dongle unit with the fuse still in place. If you do this, the alarm system will arm itself after the car has been started.
