5.Well like i already said to your colleague, i think i need a new battery in my keys as it only unlocks my car when it feels like it!!!

6.Thank you for your keys, i am going to take them into the workshop and get your new battery fitted. I should only be 5 minutes and you can get on with your day
Meanwhile 15 minutes later...
7.Sorry to keep you i got caught up in parts. All fitted ok though so your good to go. That will be £8 please, Will you be paying by card? if so would you mind making a small contribution to the Hendy Foundation?
Glad thats all sorted out, hopefully the battery was the problem and the lockings all working ok. Cant wait to meet the girls later at the party.....
