AB 486 amends Penal Code section 466 to add “key programming device,” “key duplicating device,” and “signal extender” to the enumerated list of instruments whose possession, manufacture, alteration, or repair—when tied to criminal intent—is a misdemeanor. The bill also supplies statutory definitions for those terms that reach devices able to program or delete vehicle keys, capture key codes or signals, remotely start vehicles, or amplify a key fob’s signal.
Why this matters: the amendment targets a clear enforcement gap created by modern keyless and computer‑based entry systems, giving prosecutors an explicit statutory hook to pursue tools used in contemporary vehicle thefts. It also raises immediate compliance questions for legitimate actors—automotive technicians, locksmiths, dealers, and secondary market sellers—because the statute criminalizes possession or alteration tied to criminal intent without creating statutory exemptions or recordkeeping rules.
At a Glance
What It Does
The bill revises Penal Code §466 to list key programming/duplicating devices and signal extenders among the instruments that can make an otherwise lawful act a misdemeanor when possessed or made with intent to feloniously break or enter. It defines those terms to include devices that access a vehicle’s onboard computer to add/delete keys, capture key codes, remotely start vehicles, or amplify a key fob signal.
Who It Affects
Auto locksmiths, independent automotive technicians, key programmers, dealerships, pawn shops, online marketplaces, and consumers who buy key‑fob extenders or aftermarket programming tools. Law enforcement and prosecutors will also be affected as they gain a clearer charging vehicle for modern theft tools.
Why It Matters
The change brings statutory language up to speed with technology used in vehicle thefts and provides prosecutors a direct charge rather than relying on broader interpretations. At the same time, the lack of express exemptions or implementation guidance creates uncertainty for legitimate businesses that use the same dual‑use tools.

What This Bill Actually Does
AB 486 modifies California’s long‑standing burglary‑tools statute, Penal Code §466, by explicitly naming two categories of modern, automotive‑focused tools—key programming/duplicating devices and signal extenders—as instruments that, when possessed or made with criminal intent, constitute a misdemeanor. The statute keeps the familiar three ways to violate §466: possession with intent to feloniously break or enter; making or altering a key or instrument without being requested by someone authorized to do so; and making/altering/repairing an instrument while knowing or having reason to believe it will be used to commit a crime.
The bill adds short definitions. A “key programming device” or “key duplicating device” is any device that can access a vehicle’s onboard computer to add or remove keys, remotely start the vehicle without a key, or capture a key code or signal to remotely access the vehicle.
A “signal extender” covers key fob amplifiers and similar devices that extend a keyless fob’s range to lock, unlock, access, or start a vehicle. Those definitions sweep in both specialized hardware used by criminals and tools used legitimately by locksmiths, dealers, and technicians.The statute does not create licensing, permit, or recordkeeping requirements for legitimate users, nor does it establish an explicit commercial exemption for vendors, diagnostic tools, or manufacturers.
That omission means lawful possession will turn on context and proof of intent: a dealer programming a new key at the customer’s request will be safe; an unknown person with a programming unit in suspicious circumstances may be exposed to misdemeanor charges. Because the bill keeps the offense as a misdemeanor, convictions carry criminal records and the ancillary consequences that follow for individuals and small businesses.Finally, AB 486 includes a fiscal clause stating no state reimbursement is required to local agencies because the change is categorized as altering a crime definition.
Practically, however, local law enforcement and prosecutors will be the entities most likely to use the new language, and businesses that supply or use these devices will need to decide whether to change practices—document authorizations, tighten sale controls, or alter inventory—to reduce exposure.
The Five Things You Need to Know
The bill amends Penal Code §466 to explicitly list “key programming device,” “key duplicating device,” and “signal extender” among burglary instruments.
It defines a key programming/duplicating device to include any tool that accesses a vehicle’s onboard computer to add or delete keys, remotely start a vehicle, or capture a key code or signal to access the vehicle.
A signal extender is defined to include key fob amplifiers or devices that extend the range of a keyless entry fob to send coded commands (lock, unlock, start, or other remote functions) to a vehicle.
The statute preserves the existing §466 elements: possession with intent to feloniously break or enter; making/altering a key without authorization; or making/repairing while knowing the item will be used in a crime; the offense remains a misdemeanor.
Section 2 states the act requires no state reimbursement to local agencies because it changes the definition of a crime (invoking Section 6 of Article XIII B and related Government Code provisions).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Adds automotive key devices to the enumerated burglary instruments
This paragraph inserts “key programming device or key duplicating device” and “signal extender” into the long list of instruments (picklocks, crowbars, bump keys, etc.) whose possession with criminal intent or production/alteration can constitute a misdemeanor under §466. Practically, prosecutors can now point to the statute when charging cases that involve modern electronic tools rather than relying solely on broader statutory language or case law.
Defines key programming/duplicating devices
The bill’s definition reaches any device that can access a vehicle’s onboard computer to create additional keys, delete keys, or remotely start a vehicle, and explicitly includes devices that capture key codes or signals to remotely access a vehicle. That language is broad: it sweeps in dedicated hardware used by locksmiths and some dealer tools as well as aftermarket devices sold to the public or by criminal sellers.
Defines signal extenders (key‑fob amplifiers)
Signal extenders are described as devices that increase a keyless fob’s effective range to send coded signals for locking, unlocking, accessing, or starting a vehicle. The definition targets equipment central to the ‘relay attack’ method of stealing keyless cars but could also capture consumer boosters used to extend remote start or garage‑opener range.
Preserves existing offense structure and misdemeanor classification
The amendment leaves intact §466’s structure: criminality depends on intent to feloniously break or enter, on making/altering without authorization, or on knowingly making/repairing instruments destined for criminal use. The bill does not change penalties—violations remain misdemeanors—so the practical effect is expanded coverage without escalating statutory punishments.
Fiscal clause — no state reimbursement required
The bill includes the standard constitutional clause asserting that no state reimbursement is required because the act changes the definition of a crime. That statement limits the state’s obligation to reimburse local governments for costs, but it does not prevent local agencies from incurring additional enforcement or prosecution expenses in practice.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Law enforcement and prosecutors — Gain an explicit statutory basis for charging thefts that employ key programmers or relay devices, potentially simplifying charging decisions and bridging gaps where older tool lists did not clearly cover electronic or signal‑based equipment.
- Vehicle owners and insurers — Could see downstream benefits if the statute deters commonly used high‑tech theft methods, reducing losses and claims tied to relay attacks and key‑programming thefts.
- Authorized dealerships and OEM service centers — Stand to benefit from a legal environment that targets unauthorized key programming, reinforcing dealer control over secure key provisioning and reducing fraudulent reprogramming.
Who Bears the Cost
- Independent locksmiths and automotive technicians — Face increased legal risk if they possess programming or diagnostic tools without clear, contemporaneous proof of customer authorization; may need to change workflows and recordkeeping to demonstrate legitimate use.
- Secondary‑market sellers, pawn shops, and online marketplaces — May see higher compliance burdens and potential liability for selling devices covered by the statute; sellers may restrict inventory or add stricter vetting to avoid culpability.
- Consumers using legitimate signal extenders or remote‑start accessories — Risk incidental criminal exposure if possession alone is viewed suspiciously in certain contexts; consumer access to common convenience devices may be chilled absent guidance or exemptions.
Key Issues
The Core Tension
The bill balances two legitimate goals—closing a legal gap that allows criminals to exploit modern keyless technology and avoiding criminalization of lawful professional activity—by using broad statutory additions without procedural safeguards; the result forces a choice between empowering enforcement and exposing lawful technicians, sellers, and consumers to legal risk unless additional rules or enforcement guidance follow.
The bill criminalizes possession and handling of dual‑use automotive devices without creating bright‑line exemptions, licensing rules, or proof‑of‑authorization procedures. That creates a classic dual‑use problem: tools that are simultaneously necessary for lawful locksmithing, vehicle servicing, and dealer diagnostics are now explicitly covered by the burglary‑tools statute, shifting the battleground to evidentiary questions about intent.
Prosecutors will need to piece together facts—location, quantity, packaging, transaction records, or admissions—to show the requisite intent to feloniously break or enter, and defense counsel will have potent factual avenues to argue lawful use.
Definitions in the bill are targeted but broad. Phrases like “ability to capture a key code or signal” and the description of signal extenders could sweep in legitimate diagnostic equipment, OEM provisioning tools, and consumer aftermarket accessories.
Without regulatory or statutory safe harbors for licensed professionals, businesses will likely adopt conservative compliance measures (stricter customer authorization, retention of logs, limited inventory) that raise transaction costs and may reduce availability of legitimate services. Finally, the fiscal clause asserting no state reimbursement narrows one avenue of local fiscal relief but does not eliminate the practical cost local governments and courts might incur to investigate and prosecute new categories of cases—a friction point that could produce litigation over whether local costs are truly covered by the constitutional exception.
