MANUFACTURING : ERA keeps Daleks locked out.
Meanwhile an electronic locking device, also manufactured by Willenhall-based ERA, has been spotted in Albert Square.
An ERA door digital lock has been seen in Eastenders being used by Pat Butcher to guard the takings in Albert Square's bookies.
Stephanie Sullivan, marketing manager at ERA, said: 'Given the unpredictable nature of Walford's residents and the impending return of Grant Mitchell, it's no wonder that Andy Hunter fitted a digital door lock for added security, before he fell to his untimely death from a motorway bridge.'
The ERA Codemaster is a fully mechanical digital door lock, suitable for use in the home as well as in commercial and industrial applications.
There is no wiring required for the digital lock which be easily fitted and comes in a range of colours to match door furniture. The locks, along with window and door locks, are made by the 250 staff in Willenhall.
The firm, which is around 150 years old, makes three million locks a year.
Ms Sullivan added: 'One of our locks was also seen on the Dr Who website being used to lock the Tardis.
'A few years ago, when Bet Lynch left Coronation Street and threw away the keys for the Rovers' Return they were some of ours.
'It is good to see our products being used in space and time by the Doctor.
'It shows the durability and quality of our products. You never know if our locks could keep the Daleks out, but I would like to think so
