Nothing ruins your day like pressing the START button and seeing “Key/Fob Not Detected.” The good news: many issues are quick fixes—and when they’re not, A Lenny Locksmith West Palm Beach brings the solution to you. Our mobile techs test, program, and replace push-to-start fobs on-site so you’re back on the road fast.
Quick fixes to try first (60-second checklist)
-
Replace the fob battery (most use CR2032/CR2450).
-
Hold the fob against the START button and press brake—many cars allow “backup start.”
-
Use the emergency fob slot (often in the console, dash, or under the cup holder).
-
Step firmly on the brake/clutch and make sure the shifter is fully in PARK.
-
Move other fobs/metal away (wallets, phones, key rings can interfere).
-
Lock → unlock with the fob or door button to re-sync.
-
Check the car’s 12V battery—dim lights or slow cranking means low voltage.
-
Try your spare fob if available.
