89 locks/trunk opens when others activate their remotes

[perplexed783836]

Hi I have an 89 Regal Limited 2 door and have had issues with coming back to my car with the trunk open and doors unlocked. I notice if someone uses a remote near the car it sometimes activates these locks repeatedly. Does this 89 have a keyless entry receiver somewhere on the car or is it something else picking up the signal. The engine is a 2.8. If it might have a receiver where might I find it and disconnect it. I have pulled the fuses for now, but the trunk fuse is under the hood and the door fuse runs the interior lights and mirrors and it is a pain to put in and out all the time. Also my trunk key no longer works so I need the electrical release to get into the trunk. Your help is appreciated.
