🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Cost & Options
You can buy fobs online, but: 1) Must match your exact model/year 2) Many still require professional programming 3) Cheap knockoffs may not work reliably. Some eBay/Amazon sellers offer programming instructions for DIY-friendly models.
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Tip: Consider key insurance for expensive smart keys
Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Key Programming

Key Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Key programming typically takes 15-30 minutes for professionals
