New to forum - problem with alarm and creaky tailgate noises

[grapey100]

Hi all - just came across this forum. I have a 2005 2 litre Accord Tourer. I've had it since new and love it. I recently had a problem with the alarm going off randomly so had the alarm horn removed. The alarm still goes off randomly but only flashing lights rather than a loud noise! Is there a way of permanently disconnecting the alarm function?
Also, recently the top of my tailgate (inside the body of the tailgate) has started creaking when going over bumpy raods. Any ideas on what this might be?
