BMW 5 Series key replacement in Los Angeles

BMW 5 Series keys by year

Which 5 Series key are you holding?

Since 2000 the 5 Series has gone through five distinct key eras, and they behave so differently that 'BMW key replacement' is really five different jobs. The year-by-year table on this page lists the key type, chip family and programming method for each model year. This page explains what that table means for you in practice, what we can do for each era, and where we send you to the dealer instead.

A quick way to sort yourself. A key with a metal blade and buttons in the head is the 2000-2003 E39 style. A fob that you push into a slot in the dash before pressing Start is the 2004-2010 E60/E61 style. Push-button cars with a smart key from 2011 onward are the F10/F11/F07 (2011-2016), the G30 (2017-2023) and the current G60 (2024-2026, including the i5).

Some of the data behind this page is not settled, and we would rather say so than guess. For 2004-2007 the sources conflict on which immobilizer module the car carries. For 2022 and 2023 the key part was carried over from earlier listings and not separately confirmed. For 2024-2026 we have no established chip information at all. In each of those cases we confirm the exact setup by VIN before we quote or cut anything.

What does a 2000-2003 E39 5 Series key need?

The E39 cars in our data (2000-2003) use an EWS3 immobilizer and an ID44 (PCF7935) transponder inside a remote-head key. The blade style depends on the car: HU58 four-track on earlier E39s, HU92 two-track on later ones. That is one reason we ask for the VIN instead of just the year.

The useful news is that you do not need a working key. New keys are originated from the data in the EWS module on the bench, or ordered pre-cut by VIN. The work is done from the stored module data rather than through the diagnostic port. All keys lost is routine specialist work on these cars, not an emergency that only the dealer can solve.

Plenty of E39 owners are not actually missing a key. The most common complaint is that the remote buttons have stopped working while the key still starts the car. That points to the rechargeable battery in the remote, and the chip is fine. The other common issues are worn blades, cracked key shells, and a no-start where the key turns but the engine will not crank, which can come from the key and the EWS module falling out of sync. We work out which of those you have before we sell you a new key you may not need.

What about the 2004-2010 E60 and E61 slot-fob cars?

The first slot-fob 5 Series, the E60 sedan and E61 wagon, uses an ID46 (PCF7945, Hitag2) key with a Start button as standard. You insert the fob in the dash slot and press Start. Hands-free Comfort Access was optional. Catalogs sell one ID46 key family across 2004-2010, so the key part itself does not change much through the run.

What changes is the procedure, because it depends on the CAS module in the car. Our sources genuinely disagree on which module belongs to which year. German trade sources describe CAS1 or CAS2 in the early cars and CAS3 later, while a tool-compatibility table lists CAS2 for 2004-2006, CAS3 for 2007 and CAS3+ for 2008-2010. That is why 2004-2007 are marked as conflicting in the table. We identify the CAS generation from the module itself, by VIN and part number, and never from the model year alone.

Whichever module you have, add-a-key and all-keys-lost are documented OBD procedures for these E-series cars, and neither needs a working key. One wrinkle: late CAS3+ cars can carry 'ISTAP' firmware that needs a flash downgrade before programming. That is specialist work, not a reason to go to the dealer.

What do 2011-2016 F10, F11 and F07 cars need?

These cars moved to the CAS4 or CAS4+ module and an ID49 (PCF7953P, Hitag Pro) smart key. Push-button start is standard and Comfort Access was optional. The key is a step up in complexity from the E-series, and the replacement fob costs more as a result.

Add-a-key is possible through the OBD port with professional programming tools. If every key is lost, the job usually means reading the CAS4 module on the bench. That is not dealer-only, but it is not a job for a general-purpose tool either, and it is the kind of work where it matters who is doing it. Our table shows all keys lost as possible for each year from 2011 through 2016.

Most owners we would expect to see in this era have a dead coin cell. The car shows a 'key not detected' warning, but the emergency start position still works. Before we program anything, we check the battery and the fob's behavior, because that fix is small compared with a new key.

What changes from 2017 on with the G30 and G60?

The G30 (2017-2023) uses a BDC2 body controller and an N5F-ID21A-family 434 MHz smart key with an ID49 (Hitag Pro) chip. Add-a-key is possible for a specialist, but only when you have a working key. True all-keys-lost on these cars is effectively dealer territory.

There is an aftermarket route that advertises all-keys-lost for BDC2 cars. The tool vendor's own warning says it can lock the BDC2 against future dealer keys, so we do not offer it. We would rather send you to the dealer than risk leaving your car unable to get a key from anyone. The practical advice: if you have one working key on a G30, get a spare made while you still can.

For 2022 and 2023 the key part and chip were carried over from the earlier G-series catalog listing and were not separately confirmed. Facelifted cars may use a newer fob, so we confirm by VIN before quoting.

The G60 (2024-2026, including the i5) is the current generation, with the newest BDC architecture and Digital Key Plus. We found no established aftermarket add-a-key or all-keys-lost path, and our data has no confirmed chip family for it. We treat all key work on G60 cars as dealer-only, and we tell you that on the first call rather than after you have waited.

Duplicate key or all keys lost: what is possible for each era?

The difference between a spare and a lost-everything situation decides almost everything on a 5 Series. Here is where each era stands:

• 2000-2003 E39: no working key required. Spare keys and all keys lost are both routine specialist work.
• 2004-2010 E60/E61: no working key required. Both are documented OBD procedures, with the CAS module confirmed by VIN and a possible flash downgrade on late CAS3+ cars.
• 2011-2016 F10/F11/F07: no working key required. Add-a-key through OBD; all keys lost usually means bench-reading the CAS4 module.
• 2017-2023 G30: an original working key is needed for add-a-key. All keys lost is dealer territory.
• 2024-2026 G60: original key needed and the work is treated as dealer-only.

How does 5 Series programming actually work, and when is it dealer-only?

There are three real methods in this data, and we use the word for each one only where it applies. On the E39 the key is originated from EWS module data. On the E60 through F10 cars the method is OBD programming through the diagnostic port, with the module's security data read as part of the job. On the G30 OBD add-a-key works, but only alongside a key that already works. On the G60 the data says dealer-only.

We do not pretend that a tool can do something it cannot. Where a procedure is documented, we do it. Where a vendor warns it can damage a car's ability to take future keys, we decline it. And where nobody has established an aftermarket path, as with the G60, we say that on the phone. If you call us for a car in that group, the most useful thing we can do is save you the time of a visit.

In the other direction, a dealer is not a requirement for the older cars. A 2008 E60 with every key lost is a job we handle, and the same goes for an E39 or an F10. The decision to go to the dealer should be made by the car's actual security architecture, not by a general belief that 'BMW means dealer.'

What affects the price of a 5 Series key?

We do not quote a figure on a web page, because the same model name can mean very different work. These are the things that actually move the cost:

• Generation. An E39 key and a G30 smart key are not close to the same part, and the programming effort differs just as much.
• Whether you have a working key. Adding a key to a car with one in hand is a smaller job than starting from nothing, where that is possible at all.
• The module. An E60's CAS generation, a possible flash downgrade on late CAS3+ firmware, or bench-reading a CAS4 module all add real labor.
• The key itself. Slot fob, remote-head with HU58 or HU92 blade, or ID49 smart key each have a different part cost, and facelifted G30 fobs may differ.
• How many keys you want. Having a spare made while you are already there is usually the more economical route compared with returning later.
• Whether you need a new key at all. A dead remote battery or a tired coin cell is a much smaller job than a replacement fob.

What are the most common 5 Series key problems?

The problems below come from the pattern of failures in our data, not from anything we invented. Each era has its own:

• E39: dead rechargeable remote battery with a chip that still starts the car, worn HU-series blades and cracked shells, and EWS no-start where the key turns but the engine does not crank.
• E60/E61: a worn-out rechargeable fob battery (the dash slot still reads the fob, so the car usually starts), electronic steering lock (ELV) faults that look like key failures, and a worn dash key slot or cracked fob shell.
• F10/F11/F07: dead coin cell with a 'key not detected' warning, Comfort Access door-handle sensor faults on equipped cars, and higher replacement cost for a lost fob compared with the E-series.
• G30: the same coin-cell warning, BMW Digital Key (phone or card) enrollment trouble on equipped cars, and an expensive lost-fob replacement that usually involves the dealer.
• G60: the same coin-cell and Digital Key issues, with replacement running through the dealer.

When should you call us and when should you go to the dealer?

Call us for an E39, E60/E61 or F10/F11/F07 in any condition, including every key lost. Call us for a G30 when you still have one working key and want another. Call the dealer for a G30 with no working key, and for any G60. If you are not sure, call anyway and give us the VIN. We will tell you which side of the line your car is on.
