My mum lost the key

Today we went to the park for nuthing because my mum lost the car keys and we were looking for them but we didn't find them. So I didn't get to ride my bike because it was locked in the car. Then my mum phoned my dad then he braut the spair key. Then I went home with my dad and I had my lunch. Then my mum went to the police stashion where somebody found the keys on the path way in Brootin park and how they found it is by pressing the key until the car flashes.
