This page is for drivers in Dubai whose key fob or remote has stopped working while they are away from home, whether the doors will not unlock remotely, the car will not start, or both. It is different from being locked out because your keys are missing or locked inside the car: here, you still have the key or fob in your hand, but the electronic side of it has failed.
Who This Service Is For
This service is for anyone whose car key fob or remote has stopped responding, whether that means the doors no longer unlock when you press the button, the car will not recognise the key to start, or both. It covers standard remote-unlock fobs and push-button proximity key systems, on personal, rental, or company vehicles. If your keys are locked inside the car or have gone missing entirely, our car door opening service covers those situations instead. If the doors will not unlock but the fob itself is clearly working, our car door not unlocking service is likely the better fit.
How to Tell This Is a Fob or Remote Problem
A few signs point to the fob or remote itself, rather than the car's door or locking mechanism:
- Pressing the unlock button does nothing at all, even close to the car, though the key still physically exists.
- The fob works on some button presses but not others, or only works intermittently.
- The car does not recognise the key when you try to start it, even though the physical key is present, on a push-button start vehicle.
- The fob recently got wet, was dropped, or has visible damage such as a cracked case.
- The fob has not been used in a while and the battery may simply have run down.
If instead a specific door will not unlock while the fob clearly works on other doors, that points to a door lock or central locking fault rather than the fob itself, and our car door not unlocking guidance is the more relevant page.
What Our Technician Does on Site
A mobile locksmith attending a fob or remote failure typically works through a short diagnostic process before deciding on the right fix:
- Checking whether a battery replacement resolves the issue, since a dead or weak fob battery is the most common cause.
- Checking for visible damage such as water ingress or a cracked circuit board that a battery swap alone will not fix.
- Using the mechanical key blade hidden inside most fobs to open the door manually while the fob issue itself is addressed.
- Where the fob or its programming has actually failed, discussing whether reprogramming the existing fob or supplying and programming a replacement is the right next step for your specific vehicle.
The technician assesses which of these applies to your specific vehicle and fob rather than assuming a single cause. We do not claim every fob issue can be resolved on the first visit without any parts being ordered, particularly for less common vehicle models.
Proving the Vehicle Is Yours to Access
Because this work can involve reprogramming or replacing a key that starts the vehicle, we ask for reasonable proof that you are entitled to have this work carried out, typically the vehicle's registration card, known as the Mulkiya, matching the person present. For a rental vehicle, a valid rental agreement is used instead of the Mulkiya, since the vehicle is registered to the rental company. For a company or fleet vehicle, we may need to confirm authorisation with an employer or fleet manager. This applies in the same way as it does for any car lockout, and protects you as the vehicle's driver or owner.
What to Prepare Before You Call
- Your location and whether the vehicle is in a street, a mall or building parking area, or a villa driveway.
- What exactly happens when you press the fob, and whether it has worked at all recently.
- Whether the vehicle uses a traditional key and buttons, or a push-button start with a proximity key.
- Whether you have a spare key or fob available at another location, since this can sometimes be used to confirm the fault is with the fob itself rather than the car.
- Your vehicle's registration document, rental agreement, or company authorisation, depending on how the vehicle is registered.
Why the Make, Model, and Year Matter
Key fob and proximity key systems vary significantly between manufacturers, and often between different generations of the same model. The battery type, the programming procedure, and even whether a spare replacement fob is readily available all depend on these details. Having your vehicle's make, model, and approximate year ready when you call, along with whether it uses a traditional remote or a push-button start system, lets our technician confirm in advance what is realistically possible and bring the right equipment, rather than needing to work this out after arriving.
If You Are Waiting Somewhere Public
If your fob has failed in a mall car park, at a petrol station, or another public area, it is worth moving to a well-lit, visible spot near your vehicle while you wait, particularly after dark. If the location has security staff, such as mall security or a building's parking attendant, letting them know you are waiting for roadside locksmith assistance is a reasonable precaution and can also help if you need to describe your exact location to our technician over the phone.
Why This Is Different From a Simple Dead Car Battery
It is easy to confuse a failed key fob with a dead car battery, since both can leave you unable to start the vehicle. A dead car battery usually shows other signs, such as dim or unresponsive interior lights, a dashboard that will not light up at all, or a slow, straining sound when you try to start the engine. A fob or remote failure, by contrast, usually leaves the rest of the car's electrics working normally, with the fault isolated to unlocking or starting specifically. If you are not sure which applies, mentioning both sets of symptoms when you call helps our technician bring the right equipment for either scenario.
What Happens If the Issue Turns Out to Be the Car, Not the Fob
Occasionally, what looks like a fob failure turns out to be a fault with the car's own receiver or wiring rather than the key itself, particularly if a spare key shows exactly the same symptoms. In that situation, the issue is outside what a mobile locksmith visit can resolve, and our technician will tell you plainly if that appears to be the case rather than attempting work that will not fix the underlying fault. In those cases, a dealership or auto electrician with vehicle-specific diagnostic equipment is usually the right next step, and we would rather be upfront about that than leave you with a false sense that the problem is solved.
What to Do Next
If your key fob or remote has stopped working and you are away from home, avoid repeatedly pressing the button in case it drains the battery further, and get in touch so a technician can diagnose the actual cause. The four articles below cover specific causes and scenarios in more detail.
Frequently Asked Questions
Is this the same as being locked out of my car?
Not quite. A standard lockout usually means your key is missing or locked inside the car. Here, you have the key or fob with you, but it is not working electronically. The car door opening service covers a genuine lockout, while this page covers a fob or remote that has stopped functioning.
Can you fix a dead fob battery on the spot?
In many cases yes, a straightforward battery replacement resolves the issue and can often be done during the visit. If the fault turns out to be something other than the battery, our technician will explain what is actually needed.
What if my fob was dropped in water?
Water damage can affect the internal circuit board, not just the battery, so a simple battery swap may not resolve it. Our technician can assess the extent of the damage and explain whether repair, reprogramming, or a replacement fob is the right next step.
Do you carry replacement fobs for every car brand?
Availability depends on the specific vehicle make, model, and key system. Our technician can tell you on the day whether a suitable replacement is available immediately or needs to be sourced, and will not promise a specific part is on hand before confirming it.
My car will not start even though the fob is in the car. Is that the same issue?
It can be related. On push-button start vehicles, a failed fob or a fault in the car's ability to detect it can prevent the engine from starting even though the fob is present. This is covered on this page as part of a broader fob or remote failure, alongside the doors-will-not-unlock scenario.
What proof do I need if it is a rental or company car?
For a rental car, your rental agreement in place of the vehicle registration document. For a company or fleet vehicle, we may need to confirm authorisation with your employer or fleet manager before carrying out reprogramming or replacement work.
