Differences in the BS ERA locks

[Lukekjackson]

I bought myself am ERA 5 lever lock to practice using by home made pick on, I don’t know the name of it as it didn’t seem to say it on the packaging. The main details of it are,

It’s the larger of the key shaft diameters (crap explanation I know)
Gold / brown case dimples on either side of keyway.

I mastered this one and then acquired another ERA again I don’t know the model, but the casing was very similar to the one above, the main difference is that it uses a smaller key.

What I want to know is, does anyone know what advantaged / disadvantages of the two key sizes give?

On the second lock the two levers which are closest to the bolt construction are held up by a ridge when the lock is in its unlocked state. I can’t see what this achieves and it just seems strange that it is used on the second lock but not on the first when in other ways they seem very similar.

Any input would be appreciated

Cheers

okay... the first one is an Era Invincible... this uses a 5G key.

The next one is an Era Profit, this has a 7G key.

the key sizes only really mean that you need more than 1 size curtain pick... Chris Belcher makes them all and they are apparently amazing.

The anti-picking notches are nastier in the Invincible, and it has a stronger bolt which slides out - other than this they are similar.

I’ve read a lot about the B picks and everyone seems to agree their spot on. I aim to get one at some point but as I’m not a trading locksmith I don't have the option as of yet

I was a bit put out when i realised that the second lock was a different key size, as it took me long enough to get the first pick working consistently and I had to make another.

I was wondering if their was any reason from a operation point of view for the differences or if it was just so ERA would have more models for people to buy parts for.

Hi the profit is a budget lock (cheap) but it still does the job as it is classed as a BS 3621 1998
