# How do I install or replace my part myself?

Want to fit your part yourself? Here are the principles, and the cases where it's better to call in a professional.
Many parts can be replaced yourself with a bit of method. But **some operations require a professional** — we tell you clearly when that's the case. Fitting and implementation remain your responsibility: our technical advice does not replace them.

### 🔧 Parts you can fit yourself

Seals, bulbs, remote controls, batteries, some rollers… can generally be replaced without particular difficulty.

### 📺 Our fitting aids

Aidegar provides **video tutorials** and **online instruction guides** for many parts, in particular replacing torsion and extension springs. Find all our useful content [here](https://www.aidegar.fr/content/category/5-astuces-et-conseils). 

> ⚠️ **Torsion springs: danger.** Springs, especially torsion springs, are under very high tension and can cause serious injury. **Do not attempt to remove or adjust them yourself** without the necessary tools and experience. Our experts are available 7 days a week to help you choose and fit them.
