[Micra alarm faulty]

Trevor

Is there an easy way to disconnect the alarm?

We could lock the car then which would be nice!

Thank you for your help with this matter - much appreciated

Regards

Finally tested battery.

Resting voltage is 12.7v.

14.4v with car running.

Does that rule our battery?

Are there boot and bonnet sensors?

Loud motor bikes also seem to set it off.

The car is often parked close to a bus stop so would prolonged noise and vibration be enough to trigger alarm?

My partner is convinced it's passing buses which trigger the alarm. She's positive that on several occasions the alarm has gone off as a bus has gone past the car, which is parked on the road.

Is this possible and if so, what's at fault?

I will test the battery. Just googled voltages and test procedure, all fairly straightforward.

Thanks again for assisting with this. I'll post battery test results tomorrow.

Thank you

The battery is only 3 years old - just found receipt. Still worth getting checked?

Tried locking it to see if alarm behaved but a passing bus set it off. I'd recently locked car and gave it a good rocking to try and Trigger alarm but it didn't go off. 

Is it the noise or the vibration from the bus causing the problem? Are there two microphones near the rear view mirror?

Any way of testing them?

Found radio code and all sorted. Replaced broken aerial with metal coat hanger which works nicely!

Hi Trevor

Each door brings on the interior light independently so hopefully sensors are ok.

I've cleaned battery terminals and connectors. There was no corrosion but I did feel the connectors were a bit loose when removing so nipped up them up when refitting.

Can I test the battery in any way? Take it to Halfords and ask them to test it?

A new battery in the key fob has greatly improved the range and consistency of the remote locking but I guess that won't be linked to the intermittent alarm issue? 

I do now need a code for the stereo which we don't have! Is there a default code? Tried 0000 and 1234 and now got WAIT 1HR message.

Any suggestions appreciated.

Thanks

Thanks Trevor.

I'll check battery and clean terminals and also check door sensors as suggested.

Hopefully it's something simple like the battery. I'll post my findings.

Cheers

Hi

The alarm on my 53 Micra Ancaster goes off at random times.

Where should i start looking for common issues? Can it be easily disconnected if a fix proves costly?

The aerial mast is also broken but it's not the screw in type. Can't seem to find a replacement on the usual sites. Any suggestions appreciated.

Many thanks

Rob
