The locks at London 's Olympic football final venue Wembley Stadium have had to be changed , after police responsible for security at the world-famous sports arena lost their keys . A Metropolitan Police spokesman told CNN on Monday that officers at the ground first realized the keys had gone missing last Tuesday , July 24 . Scotland Yard sent a team of detectives to the site to search for the missing set , but despite determining that they had not been stolen , officers were unable to find them . As a result , Olympic Games organizers and embarrassed police chiefs decided that all internal locks inside the 90,000-seat stadium would have to be replaced . A London 2012 spokesman told CNN : `` Keys being used by police officers on searches at Wembley Stadium were reported missing ... These were internal keys , locks have been changed and the security of the venue has not been compromised in any way . '' Police insist there is no evidence of any criminal offense in relation to the keys , and no risk to security because of their loss . `` There is absolutely no security concern in relation to the stadium , as measures were taken immediately to secure all key areas of the venue , '' the Metropolitan Police said in a statement . The cost of replacing all the high-tech laser keys used at Wembley is expected to run into tens of thousands of dollars .
