Mercedes Sprinter Key Replacement Worthing With Keys Coded at the Van
A Mercedes Sprinter key replacement is a new key cut to the HU64 blade and coded through the electronic ignition switch, and Worthing Auto Locksmith does it at the van, usually in one visit. Sprinters built up to 2018 run the FBS3 system and are covered at the kerb, and the year is confirmed on the call so nobody pays for a visit that cannot finish.

Mercedes Sprinter Key Replacement in Worthing
A Mercedes Sprinter key replacement is a new key cut to the blade the van carries and coded to its immobiliser, carried out at the vehicle rather than at a dealer. Two things decide the job. Which Sprinter generation it is, and whether a working key remains.
The Sprinter is the van a Worthing callout meets in three quite different forms. A T1N bought as a horsebox, a W906 working every day on a site, and a 2020 VS30 on a courier contract are three separate key jobs, and the difference sits in the immobiliser generation rather than in the badge. This page covers the Sprinter specifically; van key replacement covers the Transit, the Transporter, the Vivaro and the rest.
Two jobs account for almost every Sprinter callout. A spare cut while one key still works takes 45 to 75 minutes. A key built with none left takes 90 to 180 minutes, because the electronic ignition switch is read first and the missing keys are erased afterwards.
Sprinter Key Systems by Generation and Year
Sprinter keys split across three immobiliser generations and two blade eras. The table below sets every Sprinter generation against its years, its key system and what that means for a replacement key.
| Model | Years | Key system | What it means for a key |
|---|---|---|---|
| Sprinter T1N, W901 to W905 | 1995 to 2006 | Early Mercedes immobiliser | Infrared remote, blade confirmed at the van |
| Sprinter W906 | 2006 to 2013 | FBS3, HU64 blade | Spare keys and all keys lost at the van |
| Sprinter W906 facelift | 2013 to 2018 | FBS3, HU64 blade | Spare keys and all keys lost at the van |
| Sprinter VS30, W907 | 2018 onward | FBS4, HU64 blade | Higher encryption, dealer route in almost every case |
| Vito W639 | 2003 to 2014 | FBS3, HU64 blade | Priced and timed as a W906 |
| Vito W447 | 2014 to 2018 | FBS3 on most builds | Year checked before a visit is booked |
| Vito W447 | 2018 onward | FBS4 on later builds | Same boundary as the Sprinter |
| Citan | By model year | Shares the Renault platform | Quoted as a small van rather than a Sprinter |
The 2018 model year is the line that decides the whole job. A Sprinter registered before it is almost always a W906 on FBS3, and that van is keyed at the kerb. A Sprinter registered after it is a VS30 on FBS4, and that system carries a level of encryption the aftermarket does not hold. The registration settles which side of the line a van sits on, which is why it is asked for first.
The HU64 blade runs from the W906 through to the current VS30, including as the emergency blade folded inside a keyless fob, so the blade alone never tells anyone which system a van uses. Blade cutting is covered under car key cutting, for both eras.
The 2018 Line on a Mercedes Sprinter
FBS3 and FBS4 are two versions of the same Mercedes immobiliser family, and the gap between them is the difference between a kerbside job and a dealer job. On FBS3 the electronic ignition switch can be read and a new key written to it at the van, with no working key required. On FBS4 that route is closed.
A Sprinter owner is told which system the van uses on the call, before anyone sets out. That single sentence saves an FBS4 owner a wasted callout charge and points them at the dealer route with the paperwork already in hand. The same boundary applies across the Mercedes range, and Mercedes key replacement sets it out for the cars, where the changeover falls several years earlier than it does on the vans.
Mercedes Sprinter Key Replacement Cost
Mercedes Sprinter key replacement costs between £180 and £360 on a van built up to 2018. A spare cut while one key still works sits at the bottom of that band, and all keys lost sits at the top.
The table below sets the five Sprinter jobs against the time each one takes at the van and the factor that moves its price.
| Sprinter job | Time at the van | What moves the price |
|---|---|---|
| Spare key, one key works | 45 to 75 minutes | Generation and key type |
| Remote or fob fault | 20 to 40 minutes | Whether the board and battery are intact |
| Broken blade removed | 15 to 30 minutes | Which lock holds the fragment |
| Keyless fob replacement | 60 to 90 minutes | Fob supply and coding together |
| All keys lost | 90 to 180 minutes | Ignition switch read and keys erased |
Every Sprinter job is quoted in writing before work starts, and the quote covers the key, the coding and the callout as one figure. Three factors move that figure. The generation comes first, then whether a working key remains, then the hour of the callout.
Spare Sprinter Key Against All Keys Lost
A spare Sprinter key is the cheaper job by a wide margin, and on a van that carries one key it is the job worth booking early. The original stays in use throughout, both keys are tested on the van before the job closes, and the work takes 45 to 75 minutes. Spare car keys are cut at the address the van is parked at, including a yard, a site or a campsite.
An all keys lost Sprinter is a different job. With nothing left to copy, the electronic ignition switch is read for the data the new key needs, so proof of ownership is checked first. The V5C is preferred and a clear photograph of it is accepted, alongside photo identification matching the registered keeper. Lost car keys covers the same job across other makes.
The missing keys still start the van until they are erased. An immobiliser reset is carried out in the same visit for that reason, and on a van left on a street overnight it matters more than the new key itself.
How Long a Sprinter Key Takes at the Van
A spare Sprinter key takes 45 to 75 minutes at the van and an all keys lost Sprinter takes 90 to 180 minutes. A snapped blade is removed in 15 to 30 minutes and a replacement cut in the same visit.
Three things add time to a Sprinter job. Reading the electronic ignition switch on an all keys lost van is the longest single step. Erasing several old keys adds a few minutes per key. A van loaded to the bulkhead or parked where the cab cannot be worked in adds whatever it takes to clear the space.
A blade snapped in the door or the ignition is removed before anything else, because forcing it deeper turns a short job into a barrel repair. Broken car key extraction covers that step on the door, the ignition and the load area locks.
How a Sprinter Key Replacement Works
Four steps take a Sprinter from the call to a working key, and every one of them happens at the van.
Call With the Registration
Give the registration and the year. That settles the generation and the key system before anyone sets out, and it is the step that prevents a wasted visit.
Ownership Checked
The V5C or a clear photograph of it, plus photo identification matching the registered keeper. No blade is cut before that check is complete.
Cut and Coded at the Van
The HU64 blade is cut on the machine in the van and the key is coded through the electronic ignition switch. The Sprinter stays where it is parked.
Tested and Old Keys Erased
Every key is tested on the lock and the ignition, and any missing key is erased from the immobiliser before the job closes.
A Sprinter Off the Road Costs a Day
A Sprinter off the road costs a working day, and on a fleet it costs a day per van. That is the whole reason a mobile key beats recovery for a working vehicle. The van does not move, the load and the tools stay inside it, and the job finishes at the kerb in the same visit.
Out of hours matters more on a van than on a car, because a key that fails at five in the morning costs the whole day rather than the evening. 24 hour emergency auto locksmith cover runs every day of the year, and the line is answered by the same team rather than by an overnight message service.
Sprinter Campers and Conversions in Worthing
The coast road carries a large number of Sprinter conversions, and they share one problem. A camper is often bought used with a single key, then kept for years and driven a few thousand miles a season, so the one key wears quietly and fails a long way from home.
A conversion is keyed exactly as a panel van of the same year, because the immobiliser belongs to the base vehicle rather than to the habitation build. Work is carried out on a driveway, a storage yard or a campsite pitch, and a non-destructive vehicle entry opens a locked conversion without touching the door skin or the seals.
Sprinter Fleet and Multiple Van Keys
Fleet work is priced per vehicle and per visit, so several Sprinters keyed on one attendance cost less each than the same vans booked separately. A visit of four vans runs 45 to 75 minutes per vehicle once the first is done. Light commercial vehicle locksmith work covers the wider fleet beyond the Sprinter.
Every key issued is recorded against its registration and handed to the operator in writing. That record is what turns the next lost key into a replacement rather than an investigation, because the key count for the van is already known.
When the Key Turns and Nothing Happens
A Sprinter that turns over and does not start, or does nothing at all with a key that used to work, is often not a key fault. The electronic ignition switch is a separate component from the key, and a failing switch produces exactly the symptom people read as a dead key. Cutting a fresh key does not fix it.
The steering lock is a third fault again on later vans. A van that refuses to release its column, or that shows a steering lock message on the dash, is diagnosed before any key is cut, because a new key coded to a van that cannot release its column still leaves the van parked.
A remote that opens nothing while the blade still turns is the simplest of the three, and it is usually the battery or the button contacts rather than the coding. Remote car key repair is tried before a replacement is proposed, because a repaired fob keeps the coding it already holds.

Questions About Sprinter Key Replacement
A Mercedes Sprinter key replacement costs between £180 and £360 on a van built up to 2018. A spare cut while one key still works sits at the bottom of that band, and a key built with none left sits at the top, because the ignition switch is read and the old keys are erased.
Sprinters built up to 2018 run the FBS3 system and are keyed at the van, including all keys lost. A Sprinter built from 2018 is a VS30 on FBS4, which carries a level of encryption that sends the job to the dealer. The year is confirmed on the call, so an FBS4 owner is told before a van is sent rather than after one arrives.
A Sprinter key is made with no key at all on FBS3 vans, through the electronic ignition switch. The blade is cut to the van and transponder key programming then writes the new key to the immobiliser so the engine starts.
A Sprinter conversion is keyed exactly as a panel van of the same year, because the immobiliser belongs to the base vehicle rather than to the habitation build. Work is carried out on a driveway, in a storage yard or on a pitch, and a replacement key fob is supplied and coded in the same visit.
Fleet work is priced per vehicle and per visit, so several Sprinters keyed on one attendance cost less each than the same vans booked separately. A written record of every key issued against its registration is left with the operator.
A Sprinter that does nothing when the key turns usually has an ignition switch fault rather than a key fault, and a fresh key does not fix it. A blade that turns loosely or catches part way points at the barrel instead, and ignition barrel repairs covers that on the Sprinter.
