Sometimes I cannot lock my Saab properly with the key remote. If I am in a hurry this may get quite frustrating. After a while, I started to see a pattern. There was always a lorry nearby, a lorry with a remotely operated crane.
In Sweden, we recycle things like glass, paper, plastics and cupboard. The recycling stations are emptied regularly. This happens quite often when I drop my oldest son off at school. My conclusion is that the crane remote is operating on a similar radio frequency as my car key remote. It seems that the weaker car key signal gets drenched by the crane remote. When the lorry is gone, my car lock works perfectly.
Have anyone else had this problem?
