Mick Friend Posted August 12, 2011 Report Share Posted August 12, 2011 without seeing/knowing the lock I can't say - By cam what do you mean - Camlocks have their cams fixed with a nut and shakeproof washer. If its a tibbe type lock then the key being taken out early can be a problem But most likely to be wear in the lock and door alignment - the key after all just releases pins/wafers and allows a plug to rotate and pass that rotation to a device and lock/unlock - its like the old car keys - It turns and the car wont start - Why? dunno the battery is flat.....

ponsaloti Posted August 12, 2011 Report Share Posted August 12, 2011 You may have cut the key too short, in which case it would be down to you. Link to comment Share on other sites More sharing options...
Web_Engraver Posted August 12, 2011 Report Share Posted August 12, 2011 Had this problem on my own front door, happens if a key is inserted from both sides at the same time. Link to comment Share on other sites More sharing options...
windycity Posted August 12, 2011 Report Share Posted August 12, 2011 euro locks seem to cause so many problems for key cutters in general. good question gaz. what make of blank was it cut on and what make of lock. pm me if you don't want to upset any sponsors. i copied an era key today cut it on the normal 5pin blank, the lady came back and said its to thick as it would not go in to the lock. went into a era cylinder that I had. so i checked the era key and it was a lot thinner so cut it on a universal but she has not been back yet so maybe it worked ok.

Mick Friend Posted August 13, 2011 Author Report Share Posted August 13, 2011 Aha -a Euro cylinder - The cam is located by a 'cog' system (simple way to explain) two keys at the same time ? never had that, one should push the other out if they are aligned - usually cause a lock out. Cam being loose could be wear, if the key was short and was only just engaging as it returned to '0' to remove the pressure could jump back and allow the cam to slip. But usually to make the cam slip you need to remove the circlip and withdraw maybe both plugs to disengage the 'cog' - If your guy reset the cam its going to go again unless he removed the plug to get it there - just putting in the key should not do it - here are some single cylinders that have a pin that can be puished to move the cam around as several system need the cam at 90 degrees to operate switches etc, but again not in a door -so dunno why I mentioned it. My test would be to use her key and see if I could recreate the probelm if then my key did - it's my key if it's hers as well new cylinder. That'l be £10 please Link to comment Share on other sites More sharing options...
grahamparker Posted August 13, 2011 Report Share Posted August 13, 2011 It's a very common problem we usually come accross it once a week and the thing they all have in common is the cylinders are of the cheap foreign variety that have not been manufactured that well/or they have had a key cut (by others) that is to short and this will also cause the same problem. The length and shape of the end of a euro cylinder key are vital if it is to operate a euro cylinder correctly which is why i have as many original manufacturers key blanks as possible and try to avoid using ul050 or ul0054 unless i have to this has mean't very few problems for us on this matter. When a customer says they can lock (or unlock) the door but cannot remove the key this is down to the cam spinning 180 degrees and we usually recommend replacement with a new better quality cylinder.Currently we supply the Esla ng4 from keyprint as well as Cisa Astral S which has a special actuator that allows a key to be on the inside and you can still overide it with another key from the outside.The pfaffenhain,Evva dps/eps, and quite a few other high end cylinders can be modified to also allow this feature.

DC77 Posted August 13, 2011 Report Share Posted August 13, 2011 This has been talked about before:-http://www.shoerepairer.info/bb3/viewtopic.php?f=3&t=7254&p=67650&hilit=cam#p67650 I also find it common. Usually when keys have been copied mutiple times, copy the copy and copy the copy and the each duplication is a little diferent from the previous. Also common when a "universal" is involved. My advice to customers, when a new lock is fitted is to put an original key away somewhere safe, never use it and only have copies made from that key. That advice stands true for mortice and cylinder keys. I think we have all seen mortice keys that look as though they will never work yet the customer says "it works perfectly".
