Key for tenants

[Meluzyna]

As we won't get much of a pension, a couple of years ago we invested in a new-build buy to let flat on a big city which is managed by agents on our behalf.
Our original tenant has just moved out and a couple has moved in. The flat is in a block with an underground garage. They have been given two front door keys for the flat one electronic pulse opener for the main door to the building and one garage electronic opener which opens both the garage and the main door to the building.
I've just had the agent on the phone - they are asking for another electronic thingy for the main door. But why do they need one? There are two of them and they have two devices which open the main door, one of which also opens the garage door. The garage door opens from the inside by detection so even if one of them walked off with the garage opener in their pocket, the other would still be able to get the car out - they'd just need to either wait for their partner to return with the gadget or ask a neighbour to open the garage door for them to get in - but there is a free open air car park on the opposite side of the street.
Am I being unreasonable to think this is not my problem and that it's up to them to sort themselves out? I haven't been able to find out yet how much it would cost to get a new electronic opener for the main door - but going by experience, probably not far off 100 quid as it's not the gadget itself which is expensive but the security procedure to get it coded for our building.

Right. Not quite sure what it is that everyone wants but this solution seems fair and logical to me:

OP gets new fob programmed that opens both garage and main door. OP pays for this

Tenants return door-only fob to OP to keep as spare

OP then has spare key to building for emergency access. Both tenants have a fob that will allow them to access the garage and main building independently of each other.

Sounds sensible gabilan

We are landlords with a similar set up. I would not dream of asking them to share the electronic gizmos. The letting agent also has a complete set of gizmo and keys.
However we found the site managing agents were charging about 3 times the cost of going to the original supplier, so check the actual cost before you refuse.

Maybe they wish to keep the garage door fob in the car, so as to assure that they have it when they need it?

YABU. As a tenant who has twice in 2 separate rentals only been given one Chubb lock key and has been told by managing agent and LL that if I wanted more to pay - and then either I or my partner has been locked out as you can't always guarantee when you finish work - just get them the key.

You need to give them another device, and where are those neighbors that are always supposed to be available and willing , according to mumsnet

I hope you do get on to it, yabhugelyu.
I wouldn't be wanting to keep swapping a keep wih my dh.
What if one forgot? What if one works away?
Why should they have to rely on neighbours?
As a neighbour i'd be pissed at that!

gets new fob programmed that opens both garage and main door.
@Gabilan Funnily enough i was rapidly coming to the conclusion that this was the solution - to get another fob that does both doors - although it might depend on how urgent their need is, as garage fobs are probably harder to get hold of than simple door ones.
