In August 2025 Calpe’s hotels were 93.57% full, the highest figure on record. The town also had 2,958 registered tourist homes that year, with more than fifteen thousand guest places. When a check-in fails in the middle of that, there is no spare room down the road for your guest to fall back on. It has to be solved at the door.
Here is how check-ins actually fail in Calpe, and how to make sure yours does not.
1. The key box
Wall-mounted combination boxes are the most common self check-in in town, and they fail in three ways:
- Wrong code sent. Usually after a change that did not reach the booking message.
- Seized dials. Salt air and sun do to a cheap key box what they do to a padlock on a boat. A dial that turned in April can be solid in August.
- Empty box. The cleaner or the last guest did not put the key back.
Prevention: buy a key box with a cover and metal dials, check it physically every few weeks in season, and photograph the key inside it after each clean.
2. The smart lock
Smart locks remove the key, but add batteries, Wi-Fi and an app.
- Flat battery. The most common failure by far. Many models have an emergency contact or a backup key; make sure you know where it is.
- No signal. Codes that need the lock to be online fail when the router has been switched off.
- Guest confusion. The instructions assume the guest has used that brand before.
Prevention: change batteries before the season, not when the app warns you, and keep a mechanical backup key with someone local.
3. The street door nobody mentioned
In Calpe’s towers the guest often gets the flat key but not the fob for the building, or the wrong fob. They arrive at eleven at night and cannot get past the street door. A locksmith should not force a communal door; the fix is organisational: include the fob, and a phone number for the concierge.
4. The deadlocked door
The cleaner locked the flat with the key rather than pulling it shut on the latch, and the guest’s key only works one way, or the guest’s copy is poorly cut. The door is fine; the key is not. Test every copy you hand out.
A plan B that works
- One local contact who can reach the property within a reasonable time and holds a key.
- A spare key that is not in the key box.
- A locksmith already authorised to open the property on your say-so, so that a message from you is enough when the guest calls.
That last one matters when you live abroad. The guest calls you; you message the locksmith; the guest is inside, and you receive a photo of the invoice.
Before next season
A spring round of your properties catches the things that fail in August: seized key boxes, stiff cylinders, terrace sliders guests cannot lock. It costs far less than an emergency at the peak.
What we do for hosts and managers, including remote authorisation, is set out on the holiday let locksmith page. When a guest is shut out, the opening itself is covered on the door opening page.
