Car and home keys Lost Kytötie 18a - Vantaa, Uusimaa, Finland

I lost my keys while walking my dog

I have no images but I will try to describe the best as I can. I lost my keys while riding my bike going towards the city center (from the bus stop tecnologiiainstitut to the kvartal comercial center). I had them in my pocket so I guess they would fall on the street and I didn't notice. They were 1 key attached to an identification blue tag with the number 603 and a plastic door access and a 1 key attached to a white identification tag too (I think the brand of one key was ASSA) but I'm not sure. I also lost a white access card with small blue letters at the bottom. Thank you if you know anything about them.

I lost my keys on the beach. With a brown leather band attached
