I understand there are two buzzers on the 2013 RDX. One being the tailgate buzzer (Part Number 74940-TX4-A01) and a second one called Smart buzzer (Part Number 74940-SZW-003). I have located the tailgate buzzer at the driver side rear bumper but I can't locate the Smart buzzer.

Can anyone assist with the location of the Smart buzzer? I need to replace/repair it as it has become very weak.

Thanks a million!

Anybody know exactly where part is located? I crawled underneath the back bumper but cannot see it.

 

Sorry but what is a buzzer? Are these beeping indicators to let you know you left a door open or something? Or if you left the car with the keys while the car is still running?

 

it's the thing that emits a beep 'confirmation' noise (along with flashing the lights) when you lock the car using the remote.

 

I would think it would be in a similar spot as it makes sense to have them close to each other. I looked for an exploded parts diagram and although I found a few, none were specific enough to help.

I found it and was able to replace it with a part from Amazon but no change so the issue is probably elsewhere.
