A key fob is a sophisticated radio frequency transmitter programmed to communicate exclusively with your vehicle’s Body Control Module (BCM). When a fob stops working, the cause is usually one of five things — and the fix is a new battery, re-programming or a new fob.
Most remote fobs use CR2032, CR2025 or CR2016 coin cells. When the battery voltage drops below a threshold, the fob transmits too weakly for the vehicle to receive. A replacement battery often resolves the issue completely. However, a degraded battery left too long can damage the circuit board through leakage.
The rubber buttons press against metal contacts on the circuit board. Over time, the conductive rubber coating wears away. Pressing the button no longer completes the circuit. Worn contacts are not repaired on site. A new fob is cut and programmed from £150.
If the fob has been dropped, exposed to water or had a leaking battery, the circuit board may be corroded or cracked. A corroded board means a new fob, cut and programmed on site from £150.
Occasionally a fob loses its programmed synchronisation with the vehicle’s BCM due to interference or a dead battery. The fob is physically intact but the vehicle no longer responds. Re-synchronisation is straightforward for most makes and doesn’t require a new key.
In some cases — particularly severe water damage or physical destruction — the fob has failed. Aaron supplies and programmes a replacement fob, cut and coded to your vehicle on site.
Before calling: Try replacing the battery first — especially if the fob has gradually weakened over time rather than stopped suddenly. If a new battery doesn’t fix it, call Aaron. He’ll often be able to advise on the likely cause over the phone based on your make and the symptom.
How Aaron Diagnoses and Replaces Your Key Fob
Aaron always diagnoses before recommending a solution. The goal is to find the cheapest fix that restores full function, whether that is a new battery you fit yourself, programming the fob you have, or a new fob.
Describe exactly what the fob is doing — buttons not responding, reduced range, intermittent, stopped suddenly. Aaron often pre-diagnoses the likely cause over the phone and brings the most relevant parts.
30–45 minutes. Aaron comes to you with diagnostic equipment and replacement fobs for popular makes.
The fob is opened and inspected. Battery voltage tested. Circuit board examined for corrosion, cracks and burnt traces. Button contacts tested under load. Signal transmission tested against vehicle response.
Aaron explains what he’s found and tells you whether the fob needs programming or replacing, with the price for each. You choose.
The fob you have is programmed, or a new fob is supplied, programmed to your vehicle’s BCM on site and the blade cut to match.
Range test at 10m and 20m. All button functions verified. Central locking confirmed working from the driver’s position. Aaron doesn’t leave until the fob works exactly as expected.
No VAT. No call-out fee. Aaron recommends the most cost-effective option based on the diagnosis.
Representative Job: Ford Transit Fob Replacement, Rotherham
This represents a typical key fob replacement job across the coverage area — a quick diagnosis that saves the cost of a full key replacement.
A tradesman in Rotherham found his Ford Transit remote fob had stopped working completely. The van still started with the blade key, but central locking was non-functional — a problem when leaving a loaded van unattended.
Aaron inspected the fob on site and found a corroded circuit board from water ingress — likely from a wet pocket. Aaron cut and programmed a replacement fob on site and removed the damaged fob from the car’s memory. The remote was tested at 20 metres. Full function restored in 30 minutes.
