L&F masters

[ben]

Hi everyone,

I've been a collector of Lowe & Fletcher master keys for quite some time, picking them up here and there over the years. I've come to realise that there are a few duplicate keys in the collection albeit with different series numbers...e.g. G series and 21 series are the same; same with 18 series and 78 series.

I've had a look through the technical info on the L&F web site but there isn't sufficient info on there to work out which series are duplicates (or, indeed, how many different series there actually are!).

Is there a definitive list anywhere?

Cheers,

Ben

No idea how many series or master keys there are for L&F. If you're talking about 5-wafer locks, aren't there only a small number of wafer sizes, like 3 or 5? It should be quite easy to work out how many total differs you'll get if you assume some simple bitting rules, eg no more than 3 same cuts in a row, etc. Sorry if this is not what you're asking.

There's a range of different L&F locks - some are five wafer - others are 6/7/8, then there's levers, tubular ones etc etc.

The number of change keys per series is reasonably easy to figure out (e.g. series 95-97 means 95000 to 97000 = 2000 change keys and one master 95-97).

There seem to be 40+ different series (e.g. AA, 95-97, 97-99, 64, 66-68, 25-27, K, G, 78, etc). Some of these might share a key profile but have different masters (e.g. 36-38 and 97-99 are both on LF9 blank but different MK); others have the same key profile and same master (e.g. 78 and 18, both on LF55 blank - wonder why there's two series?!)

Cheers

Hi there,

These are my duplicates -

18 (which is same as 78) - I have 2 spare
66/67 (which is same as 81/87) - I have 1 spare
21A (which is same as G series) - I have 1 spare

Here's what I'm looking for -

31 (the tubular one); 93; 68; 89; 9000; 2000;800; 6600; K series; 28; 1F

Cheers!

Ben,

I have two genuine 68 L&F master keys.

Would you be interested in a straight swop for a 66 master

Kind Regards,
Brian

can anyone have a list off blanks and cuts to make l f master keys to code

[weerwolf]

heres a link to the website of L&F http://www.lowe-and-fletcher.co.uk/CATALOG/ENGLISH.HTM

The last file has a list of their key series. but no information on their masterkeys.

[weerwolf]

I forgot to mention this.
The master key for each serie has a different key profile than the individual keys. The 92 serie for example looks like an F , where the master key looks like some of the smaller Abus padlock keys.

Basically , the wafers have 2 grooves it them. The individual keys with slot into one of the grooves , and the Master slots into another groove of the wafers. Hence , a normal key with the cuts of the master key will NOT open the other locks.

For the 92 serie , there are 5 wafers with 3 possible dephts.

Im new to lockpicking and managed to pick up the following L&F masters
22, 24, 52, 53, 8D, 7D
Just wondering what they would be useful for? Like is there any specific types of locks that these keys would work on? And if I was planning on expanding this collection are there any specific ones that are more useful than the others?

I also have 3 long flat L&F master keys as well but im not sure what series or what theyre used for

aside from the flat keys you will also notice others which fit other styles of lockers, cabinets, etc, etc.

The long flat key sounds like a mk for the za/zg/zl series, these locks used to be used on garage door locks and locker locks.
Because the nozzle on the locks are different lengths, the keys have a series of cut outs to bypass wardings in the locks.
L&F regularly create new codes for desk and cam locks, ie, 18 and 78 are the same mk.
The internals are the same and the key codes are the same, they just swap the numbers around.
Best example is 92 series, there are 200 differs, most common being 92201 t0 92400, if you get a key with 92555 it is probably a 92355 key.
Because there are only a certain number of differs it is easy to create a new series, but the cuts are likely to cross match with another series.
Also, the mk's are normally on a different key section

Awesome info, i worked out the 3 flat keys are ZA, ZG and ZL
