Le verrouillage en plusieurs points am\u00e9liore l\u2019ancrage de la porte sur le b\u00e2ti et peut offrir une meilleure r\u00e9sistance, surtout lorsqu\u2019il est associ\u00e9 \u00e0 un cylindre et des renforts adapt\u00e9s.

FAQ \u2014 Serrure multipoints Questions fr\u00e9quentes avant installation. Faut-il forc\u00e9ment une multipoints pour \u00eatre bien prot\u00e9g\u00e9 ? \u2304 Pas toujours. La s\u00e9curit\u00e9 d\u00e9pend aussi de la porte, du b\u00e2ti, du cylindre, et des renforts. Une bonne serrure + bon cylindre + pose soign\u00e9e peut \u00eatre tr\u00e8s efficace. Encastr\u00e9e ou en applique : que choisir ? \u2304 Encastr\u00e9e = int\u00e9gr\u00e9e dans la porte (plus discret). En applique = bo\u00eetier apparent c\u00f4t\u00e9 int\u00e9rieur (souvent en r\u00e9novation). On vous conseille selon la porte et les contraintes. Peut-on conserver le cylindre ? \u2304 Parfois oui, mais il faut v\u00e9rifier compatibilit\u00e9, dimensions et niveau de s\u00e9curit\u00e9.
