Riser recliner mobility chair (Havant PO9)

Working last time we tried it, unfortunately the key to the controler broke so it will need replacing, will need a clean but too good to be thrown away. I need this to be collected by Monday. All paperwork and electrics presents except for the safety key which you can purchase online for less than £5 at this link https://www.mobilitysmart.co.uk/spare-pin-key-for-pride-riser-recliner-hand...
