Fobs and remotes
What we do with fobs
All of it at the vehicle. Programming pairs a fob to one specific car, so the car has to be there — which is exactly why we come to you.
-
The fob has stopped working
Battery, water, a drop onto concrete, or a pairing the car has quietly forgotten. We diagnose which one before we sell you anything.

- Transponder key programming
-
Push-to-start and proximity
Smart keys that the car senses rather than reads. New units paired to the vehicle, and the emergency blade inside checked and cut.
- Key fob replacement and programming
- Car key making, cutting and duplication

Spares, and clearing lost fobs
A second fob made while you still hold the first, and old fobs erased from the car's memory when one has gone missing.

Before you replace anything
Work out whether it is the fob or the car
Roughly in order of how often each one turns out to be the answer. Five minutes here saves a wasted call.
- Change the battery. It is the cause more often than everything below it combined. A weak cell fails intermittently first — works from a step away, not from across the car park — then fails completely on a cold morning. The cell type is printed inside the fob.
- Try the spare fob. This single test splits the problem in half. Spare works, first fob does not: the fob is the problem. Neither works: look at the car.
- Check the car's own battery. A vehicle battery low enough to upset the electronics will make perfectly good fobs look broken. Dim interior lights and a slow crank are the giveaway.
- Look for damage. Fobs live in pockets and get dropped, sat on and swum with. A cracked circuit board or a corroded contact from a spilled drink can leave the case looking untouched.
- Use the physical key. Almost every fob hides a mechanical blade, and almost every car has a keyhole on the driver's door — sometimes under a small plastic cap on the handle. That gets you into the car even when the remote is dead.
- Then think about pairing. A fob that has genuinely lost its pairing needs reprogramming to the vehicle. That is the point where you need equipment, and where we come out.
What not to do
- Do not prise the fob apart with a screwdriver. The case seams are shallow and the board sits right behind them. A dead battery becomes a dead fob in one slip.
- Do not keep pressing buttons hoping it re-pairs. It will not, and on some vehicles repeated failed attempts push the system into a lockout that has to time out before anything can be programmed.
- Do not buy a replacement fob before you know the fault. If the receiver or the vehicle battery is the problem, a new fob changes nothing.
The process
How a fob visit runs
- Step 1
You call with the car details
Year, make and model, whether it is push-to-start, whether you still hold any working fob, and what exactly it is doing. We price it on that call.
- Step 2
We come to the vehicle
Programming has to happen at the car, so the equipment comes to it. Nothing is towed and no appointment slot is needed at a service department.
- Step 3
Paired, cut and tested
We pair the fob, cut the emergency blade where there is one, and test locking, unlocking, the trunk release and starting, with you watching.

FAQ
Key fob questions
My fob has stopped working. Is it dead or is the car ignoring it?
Test it against a second fob if you have one. If the spare works, the problem is in the first fob — battery, a cracked board, water damage or worn button contacts. If neither fob works, the car is more likely at fault: a flat vehicle battery, a blown fuse or a receiver problem.
Change the fob battery before you change anything else. It is the cause more often than everything else put together. Our guide on a car key fob that has stopped working runs through the whole sequence.
My car is push-to-start and the fob is dead. Can I still start it?
Nearly always. Most push-to-start vehicles have a backup: hold the fob physically against the start button, or against a marked spot on the steering column or in the centre console, and press. Some have a hidden slot for the fob.
Your owner's manual has the exact method for your car, usually under emergency starting. It is worth reading it once now rather than in a dark car park later.
Can you program a fob without the car being there?
No, and be careful of anyone who says they can. Programming pairs the fob to that specific vehicle through its own electronics, so the vehicle has to be present. That is why we are mobile.
Can you make a spare fob?
Yes. If you still hold a working fob, adding a second one is a short, ordinary job. It is the version of this you want to be doing — on a planned afternoon rather than in a car park at midnight.
What if every fob is lost?
Then it is an all-keys-lost job: the vehicle has to accept a brand-new key with none of the originals present, which is a slower procedure on most cars and involves a deliberate security delay on some.
It is entirely doable at the roadside. Have the vehicle identification number, your photo identification and the registration ready. See what to do when you have lost every car key.
Should I remove a lost fob from the car's memory?
If the fob was stolen, or lost somewhere that identifies where you park, yes. Erasing the old fobs from the vehicle means a fob in somebody else's pocket stops opening and starting your car.
Say so when you call, because it changes the procedure we use.
Can you program a fob I bought online?
Sometimes. Some aftermarket fobs pair perfectly. Others are the wrong chip family for the vehicle, or a good-looking shell with electronics that will never talk to your car, and no amount of programming fixes that.
Tell us the exact part you bought when you call and we will give you an honest answer before anyone drives out.
My fob works sometimes and only from very close.
That is the classic weak-battery pattern, and it is worth acting on before it fails completely. It can also be a cracked solder joint inside the fob after a drop, or interference — some car parks and buildings are genuinely bad for radio.
If it only misbehaves in one location, it is the location. If it misbehaves everywhere, it is the fob.
