Unlike Western countries, you're tempting fate when entering a lift out here.
My last Condo had an emergency phone, however rather than auto-dial the lift service company or an emergency response company, it rang a handset on the wall on the 1st (Ground) floor. Not the manned Juristic office or the security hut. Tried it once, only to find someone had turned the volume down.
As @thesetat mentioned, lift doors have an external emergency release door opener. However, if the emergency response team didn't have the correct key, would explain the use of the "jaws of life".
Top Tip. Always have your mobile when entering a lift. Not 100% guaranteed to work with reception issues when inside the lift, but better than relying on the emergency phone, if there is one.
