Among the first steps to take, managing access to your home, particularly the creation of a key duplication, plays a central role. Yet, many newcomers underestimate the importance of this service, which is an essential guarantee for peace of mind and the protection of your living space. Accès & Fermetures, certified locksmith in Lyon, guides you on the best practices to adopt for effectively securing your new home. ## Why Create a Key Duplication Upon Moving In? The first step to securing a new home is to have complete control over access. When moving in, it is common for several people to have previously possessed the keys: former occupants, real estate agents, or even craftsmen who intervened during work. Quickly having a key duplication done by a recognized professional in Lyon allows you to regain control over access and avoid any risk of unauthorized intrusion. According to the Ministry of the Interior, nearly 80% of burglaries in France are committed by breaking in through the front door or using a key source. This reality makes regaining control of your locks and key sets all the more crucial. ## The Risks of an Unsecured Key Duplication There are many solutions for making key duplicates. However, not all are equal. Duplicating keys at non-specialized stores or online can lead to imperfect copies, security flaws, or worse, uncontrolled dissemination of your access. Only a certified and labeled locksmith, like Accès & Fermetures, guarantees the use of certified machines and original parts, thanks to its Picard Serrures accreditation and its Serruriers de France label. By entrusting the duplication of your keys to a professional, you reduce the risk of malfunction while protecting your home against attempted break-ins or illicit copies. ## The Importance of Transparency and Personalized Advice One of the main barriers to creating a key duplication is the fear of hidden costs or unpleasant surprises. At [Accès & Fermetures](https://accesetfermetures.fr/services-serrurier-lyon/), transparency regarding pricing is a priority. Before any intervention, a clear and detailed quote is provided to you. This approach, combined with personalized support, allows you to anticipate your needs: number of copies, security level suited to your home, compatibility with your existing locks. The quick intervention (often in less than 30 minutes in Lyon and surrounding areas) also ensures that you do not remain uncertain for too long, whether it is a standard installation or a locksmith emergency. ## Securing Your Home with Certified Products The security of a key duplication also depends on the level of protection offered by the lock itself. Choosing certified French products, installed by a locksmith partner of recognized brands, means opting for durability and compliance with current standards. High-security locks, equipped with property cards or unique codes, make duplication impossible without proof of identity. [Accès & Fermetures](https://accesetfermetures.fr/produits-et-marques-serrurerie-sur-lyon-ouest-lyonnais/) works exclusively with leading French brands to guarantee maximum security, both for individuals and professionals. In this regard, consulting a certified expert also allows you to receive advice on other exterior joinery to secure: windows, roller shutters, or entry doors. ## Key Duplication in Emergencies: Reactivity and Peace of Mind Lost keys, a slammed door, or attempted break-ins: an emergency situation can arise at any moment, especially during a move. Having a key duplication stored safely or entrusted to a trusted person helps avoid many inconveniences and limits the need for costly emergency services. In case of locksmith emergencies, the 7-day customer service of [Accès & Fermetures](https://accesetfermetures.fr/depannage-serrurier-lyon/) ensures a rapid intervention that meets quality commitments. Geographical proximity and knowledge of the local Lyon area guarantee arrival in less than 30 minutes to resolve any critical situation, without hidden fees or unpleasant surprises. ## How to Choose Your Locksmith for Key Duplication? In the face of the proliferation of online offers and fear of scams, it is essential to prioritize a local, certified, and transparent player. Checking labels, such as Serruriers de France, and brand accreditations (Picard Serrures) constitutes a first guarantee of seriousness. Accès & Fermetures provides its clients with a [detailed presentation of its services and areas of intervention](https://accesetfermetures.fr/depannage-serrurier-7j-7/serrurerie-menuiseries-exterieures-lyon-ouest-lyonnais/). To go further, it is also recommended to consult customer reviews or compare local recommendations, as mentioned in the article Why Key Duplication is Essential for Securing Your New Home in Lyon, which discusses the key role of key duplication when moving into Lyon. ## Legislation, Insurance, and Responsibility: What You Need to Know Beyond the practical aspect, managing key duplicates also has a legal and contractual dimension. Some insurance policies require the return of original keys or the traceability of copies made, particularly for new or recently renovated homes. Failure to comply with these clauses can engage the responsibility of the owner or tenant in the event of a disaster. Consulting a recognized locksmith professional, who provides a receipt for each copy or lock change, allows you to maintain the validity of your insurance contract, as highlighted by the [French Federation of Insurance](https://www.ffa-assurance.fr/actualites/vol-et-cambriolages-les-bons-reflexes-pour-securiser-son-logement). ## Complementary Solutions to Strengthen Your Home Security Key duplication is just one link in the security chain. For optimal protection, it is pertinent to complement this equipment with modern solutions: multipoint locks, additional bolts, installation of reinforced doors or alarm systems. A complete security diagnosis, offered by an experienced craftsman, helps identify the weak points of your home. At Accès & Fermetures, this diagnosis is conducted during each intervention or upon simple request, to propose solutions tailored to your budget and need for peace of mind. Additionally, according to the annual study by the Federation of Service Providers to Businesses, in 2026, 67.3% of professional service companies reported an increase in their turnover compared to the previous year. To learn more about the importance of residential security in Lyon, you can consult the updated figures on the official site of the National Police. ## Conclusion: Securing Your Move, A Choice of Trust and Serenity Key duplication is much more than a mere convenience: it is a true guarantee of security and serenity during your installation in Lyon. By entrusting this service to a certified professional locksmith, you sustainably protect your home against unforeseen events and attempted break-ins.
