Push-to-Start Fob Not Detected?

 

A Lenny Locksmith West Palm Beach

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.

Why “fob not detected” happens

  • Weak/Dead fob battery or corroded contacts.

  • Water damage or cracked board from drops.

  • Interference (RF noise from chargers, towers, or metal).

  • Immobilizer de-sync after a battery change or module reset.

  • Faulty antenna/receiver around the cabin or start button.

  • Brake-switch or fuse issues preventing the car from seeing you’re pressing the pedal.

  • Aftermarket remote start conflicts or poor wiring.

How A Lenny Locksmith West Palm Beach can help

  • On-site diagnostics: test fob signal, battery, and vehicle response.

  • Program new OEM/aftermarket smart fobs for most makes and models.

  • Cut the emergency insert key so you can unlock doors if the battery dies again.

  • Immobilizer resets/relearns when the system loses sync.

  • Replace damaged shells/buttons and install fresh batteries.

  • Transparent pricing before we begin—no surprises.

  • 24/7 mobile service anywhere in West Palm Beach and nearby areas.

What to have ready (speeds things up)

  • Year/Make/Model/VIN (photo of the VIN plate works).

  • Exact location (lot level, landmark, or cross street).

  • Photo ID and proof of ownership (for your security).

  • Any spare fob you want tested or programmed.

Pro tips to prevent a repeat

  • Swap the coin-cell battery yearly—cheap insurance.

  • Keep a silicone cover on the fob to absorb drops and moisture.

  • Store fobs away from phones and loose change to reduce interference.

  • Ask us to add a spare fob during the visit—it’s cheaper than another emergency.

  • Snap a photo of your VIN and keep it in your phone.
