### **Pros and Cons of buying a Dorman 99645ST Keyless Remote**

1. **Compatibility** This remote is designed for GM vehicles equipped with the **99645ST keyless ignition system**, including many **Chevrolet, GMC, Buick, and Cadillac models** from the late 2000s to early 2020s. It replaces the stock remote, ensuring proper functionality without compatibility issues.

2. **Keyless Entry & Start** Provides the convenience of **push-button start** and **remote keyless entry**, eliminating the need for a physical key in the ignition. This is particularly useful for modern vehicles with advanced security features.

3. **Durability & Quality** Dorman is a well-known brand in the automotive aftermarket, known for producing **reliable, high-quality replacements** that meet or exceed OEM standards. The remote is built to withstand regular use without frequent malfunctions.

4. **Easy Installation** Designed as a **direct replacement**, it should fit seamlessly into the existing system with minimal effort. Most users can install it themselves without professional help, though wiring may require some basic electrical knowledge.

5. **Security Features** Includes **rolling code technology** to prevent unauthorized access, reducing the risk of theft compared to older, less secure remotes.

6. **Warranty Coverage** Dorman products typically come with a **limited warranty** (usually 12 months), providing peace of mind in case of defects.

7. **Cost-Effective** Compared to purchasing a new OEM remote, this aftermarket option is **significantly cheaper**, making it a budget-friendly solution for replacing a lost or damaged remote.

---

1. **Limited Vehicle Compatibility** While it works for many GM vehicles, it **does not fit all models**. Always verify compatibility with your specific vehicle s year, make, and trim before purchasing to avoid buying a non-functional remote.

2. **Potential Learning Curve** If you re unfamiliar with keyless ignition systems, setting it up correctly may require **reading the included instructions carefully**. Some users report minor issues with pairing if not done properly.

3. **Possible Signal Interference** Like all keyless remotes, it can be affected by **electromagnetic interference** from other devices (e.g., garage door openers, cell phones, or other electronics), though this is rare with modern rolling-code systems.

4. **Battery Dependency** The remote relies on **battery power** (usually a CR2032 or similar). If the battery dies, the remote will stop working until replaced, which can be inconvenient if you don t have a spare.

5. **No Additional Features** Unlike some newer remotes, this is a **basic keyless entry and start unit** without extra functions like **remote engine start, panic alarm, or smartphone connectivity**.

6. **Quality Variability** While Dorman is generally reliable, **counterfeit or low-quality knockoffs** exist in the aftermarket. Always purchase from **authorized dealers or reputable online retailers** to ensure authenticity.

7. **Potential Void of Warranty** If your vehicle is still under **factory warranty**, installing an aftermarket remote may **void certain coverage** related to the ignition system. Check with your dealership before proceeding.
