Buying Guide: Key Purchase Considerations
What should you consider before buying a car keyless entry system?
- Vehicle compatibility: Check power door lock type (electrical vs pneumatic), 12V systems, and whether the kit supports all doors you plan to upgrade.
- Remote range: Consider how far you typically park from your car; kits vary from 50–80 meters to longer ranges.
- Additional features: Alarm, remote start, trunk release, and auto-lock timing add convenience but may increase installation complexity.
- Installation complexity: Some kits are plug-and-play, others require wiring to ignition, horn, or body computers. Assess whether you’ll install yourself or hire a pro.
- Reliability and maintenance: Look for kits with solid control modules and durable remotes. Consider weather resistance for remotes and wiring.
