Hi all, I’m new here and have a question about the keyless entry system

where are all the antenna/aerials located? My car is a 2013 Sq5.

It’s recently had the rear bumper removed for repair. Since getting the vehicle back the key fob range to lock/unlock is down to a few yards, fob also has new battery.. the door handle keyless entry has also become intermittent.

i know there is one antenna or aerial inside the trunk just above the toolkit behind plastic mouldings (the garage is looking at replacing this)

However, are there any within the bumper, or elsewhere I should know about? Also anything which I could mention to the garage

if anyone can help that’ll be great. Any diagrams to show locations even better!

thabks in advance guys
