Vanguard left hand patio door handle turn knob broken

Vanguard left hand patio door handle turn knob broken

I replaced my latch recently on sliding door and it was working fine until the door lock knob started to spin and eventually broke with the door being left in place locked. I don't know how to get this off so I can replaced it. The door is locked and there is not way for me to unlock it. Any suggestions welcome.

Hi Gurdeep;

You have a patio door made by Vanguard a window and door company thats very popular in California.

The handle they use is made by RotoFasco and always has problems because a small plastic lever inside the mechanism breaks.

Yours is the first I have seen with a broken knob but its only held on with a soft steel rivet so it does not take much for it to work loose and eventually come off.

You can see my page about Vanguard patio door handles here

You will find an advertisment for Amazon on that page for the handle. Your handle is a left hand

Unfortunately you have to buy a kit with both inside and outside handles plus the lock. Its not possible just to buy the inside handle.
