CAR KEY FOB REPAIR

Modern car key fobs (remote keys and smart keys) are sophisticated pieces of technology, but we are entirely up to date on the latest systems. Our team can repair and program fobs for virtually all makes and models – cars, vans, motorbikes, and even HGV lorries. Here's what our key fob repair service covers:

REMOTE LOCK/UNLOCK ISSUES

If your car isn't responding to the remote, we'll diagnose whether the issue is with the fob or the car's receiver. Often, reprogramming the fob or replacing the internal transmitter can fix remote communication problems.

TRANSPONDER CHIPS

We handle transponder key issues, from re-flashing immobiliser chips to cloning and programming new ones. If your engine doesn't start due to a key fault, we can re-code your keys or supply new coded keys as needed.

BATTERY REPLACEMENT & SOLDERING

Some key fobs have soldered rechargeable batteries (standard in brands like BMW, Mercedes, etc.). We carefully open sealed units and replace batteries for you. We also repair or re-solder any loose components on the circuit board.

UPGRADES & REFURBISHMENTS

If your key is severely damaged, we can often refurbish it completely – with a new case, new blade, new buttons, and a refresh of the electronics. The result is essentially a like-new key fob.

All our key fob repairs include free diagnostic testing. We verify that your repaired fob sends the proper signals and that it's fully synced with your vehicle before we leave. If needed, we'll guide you through any necessary steps; typically, however, the process is handled seamlessly by us.

COMMON CAR KEY PROBLEMS WE FIX

Car keys and remotes are subjected to wear and tear every day. Our car key repair service can fix almost any issue, including:

BROKEN OR SNAPPED KEYS

If your key has snapped in the ignition or door lock, or the blade has broken off the fob, we can extract the broken piece and cut a new key blade on-site. A common issue is keys that snap due to metal fatigue or bending, especially older keys. We'll refurbish or replace the blade so it works like new.

WORN-OUT KEY BLADES

Keys (especially high-usage keys) can wear down over time until they no longer turn the lock. Rather than jiggling a worn key, let us cut you a fresh blade to the manufacturer's specifications. This often solves problems with ignitions not turning, as a worn key or worn lock cylinder can cause starting issues. We'll diagnose and remedy the cause, whether it's the key or the lock.

DAMAGED KEY FOB CASES

Car key fob shells can crack, split or get damaged after being dropped. A cracked case can further expose the electronics to damage. We stock replacement remote cases and shells for most car makes. Our technician will transfer your internal circuit into a new durable case, replace any worn buttons, and refit or cut a new blade if needed – giving your key fob a second life without the cost of a whole new key.

FAULTY OR WORN BUTTONS

Do you have to press your remote buttons multiple times to lock/unlock your car? Worn-out rubber buttons or faulty micro-switches are a very common issue we fix. We can repair or replace unresponsive buttons and internal switches on your key fob so that every press registers. No more struggling to lock your car – your remote will work reliably again.

KEY FOB BATTERY & ELECTRONIC FAILURE

If your key fob has stopped working or works intermittently, the culprit could be a drained battery or a failing transponder chip. We replace key fob batteries on the spot and test the fob to ensure it functions properly. If needed, our experts can also reprogram or re-sync your car remote to the vehicle. In cases of electronic component failure, we'll advise you if a repair is possible or if a new fob module is required. Often, reprogramming the existing key can restore a non-working fob without a full replacement.

WATER-DAMAGED KEYS

Dropped your key in water or put it through the washing machine? Electronics and water don't mix, but don't panic – we have a success rate at rescuing water-damaged car keys. We will carefully open the key fob, clean and dry the circuit board, and assess for any fried components. If salvageable, we'll get it working again. (Note: severe water damage or corrosion might require a replacement, but we'll always try a repair first if economical.)

VEHICLE NOT DETECTING KEY

If you have a push-button start car that suddenly isn't detecting the key or an immobiliser light blinking, it could be an issue with the transponder chip in your key. Our skilled technicians can diagnose these issues – whether it's a key that's lost its coding or a sensor fault. We can often re-code or replace the transponder chip and pair it to your car's ECU, restoring functionality. This is far quicker and cheaper than towing to a dealer for a new programmed key.

In many cases, repairing a broken car key or fob is more cost-effective than purchasing a new one. It's often just the casing or a small internal component that fails. By fixing that instead of replacing the whole key, you can save a significant amount. We aim to save you money and get you moving again without delay.

FREQUENTLY ASKED QUESTIONS ABOUT CAR KEY REPAIR

1Can my broken car key be repaired, or will I need to buy a new one?

In many cases, we can repair your existing car key. Common issues, such as broken blades, cracked cases, and worn buttons, are all fixable with the right parts and expertise. We will always try a repair first, as that is more cost-effective for you. If the key's electronic components are severely damaged (for example, a completely fried circuit board from water or fire damage), then a replacement might be necessary. Rest assured, our van is stocked with both repair parts and equipment for on-site key cutting and programming, so we'll provide the solution that is best for you. Our success rate with key repairs is very high, saving customers time and money.

2How long does a car key repair take?

Most car key repairs are completed in well under an hour. Simple fixes, such as swapping a case or replacing a blade, can be done in minutes. Even more involved repairs, such as soldering new buttons or reprogramming a transponder chip, typically take 30 to 60 minutes. We come to you and do it on the spot, so you don't have to wait days for a dealer or mail-in service. Many keys can be fixed during a single short visit, getting you back on the road almost immediately.

3What if my key is lost or too damaged to repair?

If you've lost all keys or your broken key can't be salvaged, we can switch to a car key replacement service on the spot. We can cut and program new keys for your vehicle right at your location. This includes coding new transponders and remotes. We carry a large inventory of blank keys and fobs in our vans. So even if repair isn't possible, you won't be stuck – we will provide you with a brand new key and pair it to your car, all in one visit.

4Will my repaired key be as good as new?

Yes. We aim to restore your key to full working condition. We use quality replacement parts – often the same or an improved version of what the manufacturer used. For instance, if your key's case is flimsy and cracked, the new replacement case we provide will be robust and durable. If the buttons were worn, new buttons will make it click like new. We also thoroughly test every function (remote locking, manual turning in the ignition, starting the car) to ensure it works reliably. In many cases, clients tell us their key feels brand new after our repair and refurbishment service. Additionally, we back it up with our warranty, ensuring your confidence in its longevity.
