keysinthecity Posted July 29, 2016 Report Share Posted July 29, 2016 Do you ever get this? We get it occasionally. Switching to HD seems to resolve the issue. Link to comment Share on other sites More sharing options...
Mike at Vauxhall Posted July 30, 2016 Report Share Posted July 30, 2016 I'm sure I'm not the only complete business slag in the the forum. I'll buy blanks from anyone. JMA blanks I've found to fat and changed to hd. Ing s Un 11 Eva 1d Corbin blanks. Never had a problem with. lately had an issue with er2d. Not enough to change supplier yet, but hd ul2 worked a treat . Both sks and davenport are important to me. Fairly certain someone will start banging on about how good silca blanks are !

grahamparker Posted July 31, 2016 Report Share Posted July 31, 2016 I have used Silca for 35 years and can count on 1 hand the problems i have had. I usually only stock other blanks if Aldridges are out of stock of a Silca blank. I have had to swap to JMA/Keyline for dimple blanks as the price difference is HUGE and i have not had a problem with any yet. Link to comment Share on other sites More sharing options...
canoncan Posted August 1, 2016 Report Share Posted August 1, 2016 Yes. I've had a few COR1D's come back that wont go into the lock. I now use Silca CB6 Link to comment Share on other sites More sharing options...
NYKeys Posted September 16, 2016 Report Share Posted September 16, 2016 I have used Silca for 35 years and can count on 1 hand the problems i have had. I usually only stock other blanks if Aldridges are out of stock of a Silca blank. Is it that Aldridge are expensive compared to SKS for blanks or just that Silca are quite a bit more expensive? I realise that selectively it's probably worth going for Silca just wondering if one can negotiate discount or price break terms with Aldridge Link to comment Share on other sites More sharing options...
grahamparker Posted September 16, 2016 Report Share Posted September 16, 2016 Silca are the most expensive key blanks to buy, but i think i can count only 3 times i have issues with a blank not fitting in the last 30 years of using them. Aldridges discount only applies to boxes of 50 and above. Link to comment Share on other sites More sharing options...
k4mrc Posted September 16, 2016 Report Share Posted September 16, 2016 There are more than one Corbin blank, HD supply about 4 (I think) CB7 being the most popular but occasionally (count on one hand) they have not gone into the key hole, But it's not because of the CB7 I picked it up instead of the right blank! I will try and post on here tomorrow the key number's use the right blank and you will not have these problems. Link to comment Share on other sites More sharing options...
brightonkeys Posted September 17, 2016 Report Share Posted September 17, 2016 use the right blank and you will not have these problems. No, this is wrong. The "same" blank can differ widely between manufacturers. Link to comment Share on other sites More sharing options...
k4mrc Posted September 18, 2016 Report Share Posted September 18, 2016 No, this is wrong. The "same" blank can differ widely between manufacturers. No, this is right - exactly what I'm saying, use the right blank for the right key and your there, Link to comment Share on other sites More sharing options...
brightonkeys Posted September 19, 2016 Report Share Posted September 19, 2016 As a fan of the caliper yourself, locksafe, I would have thought you would agree that the different blank manufacturers do not make blanks of identical dimensions. My experience has shown that they differ slightly. Sometimes a slight difference is bad news. That was my point. If I'm wrong about this I will have to bin my £15 digital caliper and buy a £200 one.

Count Muppet Posted September 19, 2016 Report Share Posted September 19, 2016 My thoughts about that were that the manufacturers were making blanks that fit the locks but not making them exact so that they avoid patent/copyrite issues. There definately seems to be differences between manufacturers on the same blank, but if it's too thick it's because it's the wrong blank for the lock.

grahamparker Posted September 19, 2016 Report Share Posted September 19, 2016 The problem is that everyone assumes if a key will not go in it is to thick rather than it been a slightly different profile. We have a Yacht club at Covenham resevoir that uses a Corbin lock that requires a Silca CB19 blank rather than a CB6. They had been all over the place getting keys cut that would not fit and no one realised they did not fit as the profile was wrong. Luckily they where recommended to use us and we have since cut 100's of them. kobblers 1 Link to comment Share on other sites More sharing options...
Silcaltd Posted September 19, 2016 Report Share Posted September 19, 2016 If the blanks are nickel plated this could be the problem. The plating process has to be carefully controlled otherwise the blanks end up too thick. kobblers 1 Link to comment Share on other sites More sharing options...

HD are brass so perhaps we have less hassle because of? kobblers 1 Link to comment Share on other sites More sharing options...
mrkeys Posted September 23, 2016 Report Share Posted September 23, 2016 HD CB7 JMA COR 1D SILCA CB6 All listed as same blank yet HD CB7 is without doubt thinner and does work more locks Link to comment Share on other sites More sharing options...
Flash Posted September 23, 2016 Report Share Posted September 23, 2016 No, this is right - exactly what I'm saying, use the right blank for the right key and your there, So, a customer brings in a JMA Cor 1d, I copy onto a JMA Cor 1d, it does not go in, Why?

grahamparker Posted September 23, 2016 Report Share Posted September 23, 2016 Inconsistency in the manufacturing process. The other reason is that the key is not lining up with the plug correctly and some blanks although they fit can seem as though they will not go in they are been inserted a little to high or low in the plug or at a slight angle. I had a customer a few months back said a Mila key we had cut (using a genuine blank) would not fit, as it was on my way home i popped to have a look and the key went in both sides perfectly and worked as it should, when she tried it again it would not fit i had to move the key down a little and then she could use it. The new blank had not worn and the tip was catching a part of the profile stopping it fitting in. I did it 3 more times then she finally got it to fit she was pushing it hard at a slight angle so there are other reasons. I have been to the Silca factory and seen how thorough the production process is and how often they measure and recalibrate the machines used in the manufacturing process. Yes they are probably the most expensive but how many times has someone complained on this forum about a Silca blank not fitting ?. Link to comment Share on other sites More sharing options...

I understand most of these problems Graham, I have seen them many times, I was suggesting that there are many reasons why the key does not enter the lock, even if the correct blank has been cut. No matter how much measuring with callipers or vernier gauge there will always be the rogue key to keep wind you up. kobblers 1 Link to comment Share on other sites More sharing options...
